i think it's gonna happen quicker than we think. once people start exchanging goods/services with crypto it's gameover. at some point, the vast majority will simply move their assets outside government control and refuse to pay taxes. governments will be reduced in size because most of current administrative bullshit and trade laws and tax systems etc will be redundant (at least half of government except military, pd, fd). people will have control over how much tax government really deserves. it's almost too good to be true, but so was the printing press and voting rights. it's coming. the only question is when :)
