Yes, I had proposed a "wind sock" style solution, for the gathering of smaller matter. Gravel-type should work well with this, as should dust and independant smaller debris particles.
The idea behind the launchers wasn't to get full distance out of them(tho it'd be nice if they can) but instead to reduce the Delta-V involved with setting off in a direciton massively. The "complexity" added to this operation I feel is justified by the savings in fuel if we are required to rely on propellant and general saving of time otherwise.
Yes, the general idea was to move the debris that weighs tens of kilos to the machines that weigh hundreds of kilos. This should, by my math, be far more cost effective than steering the hundreds of kilos of machinery towards the tens of kilos of debris. Some certainly will be a lot heavier, but with the way orbits tend to work intercept it at the "right" point in space and time then lend it some energy and it can be pushed/pulled to throw itself to where it needs to be quite cost effectively.
With regards to asteroidial mining then the centrafugal launcher is to reduce cost of the return journey for the material, and as this can be used over and over again I also feel it's a sensible move. The intent was to "park" facilities nearby and tow asteroid to them - Obviously starting with the smaller, and more accessible material - Getting facilities right into the belt isn't likely to be viable and result in rapid destruction until it has been sufficiently thinned. It should be able to remain relatively static for some time before it's managed to exhaust the local area, and then movement closer makes sense - but this should take hundreds of years, and by this time there should be thousands if not hundreds of thousands of such machines eating away.
Sending unmanned craft has always been my proposition so cannot be more simple than itself, and this does not within itself mitigate the requirement for servicing, or for a support network. Luckily, my proposal lays down it's own support network as it expands.
Logically, sharing will only take place with those who would want it - and due to the frequency of launches it's reasonable to expect someone somewhere will want to get something up there and not want to pay for a full launch. As previously mentioned, we can have the launch and share our excess space loading up things like cubesats from universities etc. Should needs must then various initiatives can roll out in order to pay for the entire lift ourselves - worst case crowd funding can result in applicable funding without significant trauma.
I outlined lots of things in "my plan" - nothing in the plan relies on them before they are actually there, however. There is no particular fail here becuase it is not impossible to make it exist, it's just the actuality of designing and physically building - which will make a lot more sense a lot closer to deployment time.
Your translational skills may require some attention. I had meant precisely what I had said. You desperately require education as this is a well documented topic, with many peer reviewed papers and very little of it tends to support your suppositions.
If you think avoiding needless expenditure of time and effort would make me a moron you may be good to review this entire thread for your input. If there is something specifically you would feel I have "no clue" about then feel free to provide me with some explicit details you'd require correction with. As it is not myself that has continually demonstrated a failure to understand I predict attempts at this would only really serve to highlight your own defective thinking and lack of ability to entertain valid or sufficient research on the topic.
I'm not seeking financial backers for any of my projects. Ergo this cannot lessen the chances for finding them. I have potential solutions to almost every problem. In most cases multiple potential solutions. This is the entire reasoning behind not solidifying designs at this stage - it leaves the largest number of solutions selectable, and the non-commitence would prevent introducing "features" that would make other, yet unfulfilled solutions problematic.
Obsolete is a valid descriptive term - but so is redundant. It's use is not solely multiple systems for providing failover. Failover capacity is a good thing in terms of individual systems, commonly. However, when 95 kilo of the "vessel" is ion engine and xenon tank this is useless and simply additional weight if it has a functional EM-drive. All the effort gone into making your design around that system is instantly wasted. Or designing around an NEXT-C and when it comes closer to the event we've scaled down VASMIR technology and are using that. Until a solid direction is decided a design built around is unfeasible, and deciding in finality right now would be rediculously stupid, there are many things that can happen between now and then.
As to the question of the launchers, it does matter. Or you would of removed the menton from your post instead of later mentioning to ignore it - so I highlighted your failure in being able to think anyway.
Everything in "my plan" allows for the abolishment of money. Commonly it's accepted that the only real purpose of it's existence - apart from controlling the easily corruptable - is to meter out the finite resources available to hand. If you had bothered to educate yourself in the field of economics you would understand what a supply/demand graph is, and how to read one which would of saved you highlighting your ignorance yet again.
I have no need to focus on why money is so popular now - the lack of foresight available to the common individual combined with mistakes of a few thousand years previous that wasn't realised until it overly saturated will do little about things now, especially as those able to see the problems tend collapse into futility of being immersed and enclosed in such a system.
As you appeared to intentionally avoid noticing, this initative would put everything in place to feasibly deploy an economic system that doesn't rely on a money for a catalyst for trade, by providing raw materials and finished goods to a scale that's possible to attribute to the masses on demand, without recompense.
