So your argument requires the US being the first empire to maintain a consistent tax policy for millennia, while we watch the heirs of billionaires hoard all this wealth and enjoy living in the lap of luxury (and assume they won’t manage to change the rules sometime between now and the end of time)? It’s not convincing.

Also, couldn’t you make the same argument that wage income, and every other kind of tax should be deferrable if the money gets invested? We should all just not pay the government and the government should give us an IOU until eternity? I suppose the modern monetary theory people would be on board.
