Fungibility problem: Why not just make all transactions "joined" by default

[pereira4]

So Coinjoin acts in away where inputs and outputs are all mixed up so no one can know who is sending what, pretty cool, but it's a pain in the ass to use the service, I still have no idea how it works. Why not just have this nicely integrated in the wallet? if not default then optional, but in the wallet, please don't make people have to leave their wallets to do some weird geek stuff.

If we want Bitcoin to be p2p cash like satoshi wanted to, we need to consider all of this and make it as easy to use as possible.
