The Constitution contradicts itself.  It states that citizens have inalienable rights and also says that citizenship can be revoked.  An unalienable right would be guaranteed citizenship.  Where can a citizen vote no for the Constitution? I am asking all Asgardians to oppose the current proposed Constitution until Citizenship is for life unless renounced by the Citizen.

That is a good point. For a digital nation that is asking for €100 for citizenship that's a pretty big oversight. 

Another issue I was thinking about is that for some countries, Brazil and USA for example, taking voluntary citizenship of a foreign nation is possible grounds for loss of the original citizenship. Which is not a problem now, but should Asgardia gain official recognition...
