CT and schnorr sigs will make btc fungible.
Cryptocurrency is NOT fungible. You're trying to make believe that if coins can be tumbled it's somehow fungible but there is more to it than that. If anything about the protocol at all can be altered via a strongman or banana republic voting to take over it's exposed power vacuum it's not fungible. Anonymint even agreed on this at one point in time but he has probably cucked out and did a 180 now that he wants to release a cryptocurrency of his own.
Money = has objective, static traits
Currency = random arbitrary bullshit some guy makes up and constantly fiddles with like fiat or bitcoin. If it's possible for your money to "hard fork", or randomly morph from one thing to another, it's not fungible, and hence not money. In that circumstance you are involved in some type of scheme with a schemer ruling over you.
It doesn't matter if said forks are orchestrated by a banana republic of miners in a voting process. There is no Nash equilibrium in cryptocurrency, only a power vacuum to be filled by a top down hierarchy or strongman. To escape this master and servant hierarchy you have to use real money that cannot be altered or tampered with by third parties.
