Like stocks? We know whether companies are managed well or not based on whether stocks go up and down. Perhaps allowing citizenship to have market value will help people judge whether their elected officials are doing well or not.
Also, if you don’t like it here, but everyone else does, just sell your citizenship with high value and move out.
Currently if you don’t like your country you just lost the citizenship. Also war is fought between Israel and Palestines over who should be citizen and have power to vote.
Why not trade that?
