So it's utility is for sketchy (but not too sketchy!) merchants in which a much cheaper wire transfer or free visa/mc payment would be unacceptable, but not illegal because it's a permanent public record of the transaction. Got it.
I mean, yes, they exist. And the public record is fine because you just create a new address for every transaction and cash out. Just because phone companies keep a record of who's calling who doesn't mean phones aren't useful for crime. You just use a burner phone in the full knowledge that the police can track you down, but won't because you're small fish doing minor crime.
To take one example, the global counterfeit brand market is worth trillions. They don't trade exclusively or even mainly in BTC (mostly you'd sell with physical cash), but they do use it for the reasons I mentioned above.
