Tax what? To what extent? Their Bitcoin income, how? Same principle as war: what resources will they use to surveil and steal from cattle? If they go after other asset classes that are easier to tax (equities and real estate) then that forces capital to flee to Bitcoin, which is more tax resistant, thereby further reducing their revenue…that they would use to surveill and steal. It’s a doom loop. IMO the last and eternal tax will be real estate because you can’t move or hide it, but it will be insignificant relative to today and insufficient for funding wars.
