I think that bitcoin needs to think about further taxation, because this will be a problem for its owners
Hands off approach should be taken. And anything that happens within crypto open-decentralized networks is not subject to LEGALESE jurasdiction. Only their fiat gateways/Legal corporations, because you trade your crypto for fiat currency (TENDER FOR LAW, LEGAL TENDER, Debt in transit) which has rules (jurasdiction) attached to it.
my reply to op:
Privacy / fungibility... one and the same...
this is being addressed and I'm sure it will be... but keeping the decentralized/trustless model is key also, cross-chain liquidity in the form of decentralized exchanges and atomic swap contracts that preserve/improve privacy also.
without privacy there cannot be fungiblity/freedom
We're supposed to be disintermediating the LEGAL jurisdiction, not attempting to merge with it, if we have privacy, no problem.. if we don't, lots of dystopian potential for those who do not know what Legalese/Legal/Law society is.
