Okay, so… there is a way. You can value things by tax auction. - first every owner self-values their assets at $V and pays X% of $V - then an interested buyer bonds $W>$V earnest money - then the owner pays Y% of $(W-V) or the buyer gets it for $W plus tax of Z% Rates around 1% could replace all other taxes in this scheme. Do I think it’s a good idea? I don’t know. Recipe for bureaucrat moral hazard.
