just to sort out some of the details.
the "country" is only 7km
2 and cannot actually physically house what the founder says as:
My goal from an early age was to bring more Liberty to this planet through opening up people’s minds. Today we have almost half million people interested in living in a truly free country. I would like that number to rise to a couple of million next year.
to put it into prospective liberland wants to (in the founders quote) become more densely populated than Macau s.a.r
Macau S.A.R. population: 453,125 square miles:6 population density per square mile: 73,350
instead i believe its real utility is mainly to be used as a shell company hub and tax haven. thus avoiding certain things by having personal trusts, businesses, etc set up from this "country"
this wont make people have immunity while travelling around the world in any way. (you can still get arrested in america for american crimes while your in america even if a citizen of liberland)
but will atleast secure "businesses" and "personal property" left on the land of liberland, as long as international law treaties signed by liberland are not created.
