You are making up your own clown theory and its ridiculous.
You just said that dollar bills are not fungible money which every definition gives as example of fungible money.
You are just writing ridiculous BS.
Per your own clown definition of fungible money it seems only Monero must be fungible, although we have seen traceability on Monero.
I have already said countless times that no one can stop anyone accepting Bitcoin because Bitcoin is decentralized peer-to-peer Freedom Money and 1 Bitcoin = 1 Bitcoin.
Bitcoin is fungible money. And your BS argument about tainting is refuted via coinjoins and #Lightning. Thats it.
