Yes you got me there. But how is the basic income idea implemented? Everyone loses x% every year to the 'goverment account'. Then what? How do you imply a fair redestribution of these (let us be honest) big relative amounts?
Well going by how UBI is supposed to be implemented. The amount retrieved from a 3.5% tax would be equally distributed to all wallet addresses whose identities are verified. I don't have any specific details on how we verify users so people only have one wallet account per person. Whatever organization who has the government account would have to record wallet addresses whose identifies are verified by phone number, email address, Social media accounts, etc? Proving your identity will be the big challenge to tackle.
