  It may not be de jure fungible but for most practical purposes it is. As in, when you go to exchange it for money or something else, most people don't care about which coin you give them. In my mind this makes it de facto fungible.

  You're spot on. It's possible to trace every wallet a coin passed through. If your coin ever passed a blacklisted address, it's tainted and nobody will accept it. Exchanges are already rejecting deposits containing coins that passed through mixing services. Monero is fungible because it's private. Every transaction is signed by lots of users and nobody can tell where the coins are actually coming from. There's no way to tell them apart.

    Fungibility implies interchangeability not privacy.

      In monero's case, the blockchain privacy is what provides fungibility. The fact nobody knows where the coins are coming from makes them interchangeable.

        That's a nice feature but it doesn't change that for most practical purposes bitcoin is fungable.
