No, there are no other real applications for these mixers. The only reason you even need to do that on a public blockchain is because the design of them is so bad that there's no other practical way to have privacy without enabling large amounts of criminal activity. If you really care about privacy, and you don't like criminals, then just don't use any blockchains or cryptocurrency.

This is not the level of comment quality I would expect on HN. You can do better.

Sorry but I try to avoid dumping huge amounts of information on people in every comment, that often doesn't go down well either if you can imagine. If you want more I'll elaborate. There is no possible way you can deploy this service anywhere while effectively complying with AML laws. It isn't going to work. But it's also the only real effective way you can obscure the source of transactions on a blockchain that's forced to be public. There's no reason transactions need to be forced public in the first place, other than how blockchain designers insisted it was a fundamental design parameter, when you probably agree that it isn't and that some transactions should be private by default. The simple solution is to avoid all blockchains and cryptocurrency altogether. Yes, they are that bad. I wish it wasn't true and I could say something good about them, but I just can't after watching 13 years of bad things happen.

And no, things like monero and zcash aren't a working solution to this problem either, that's a whole different discussion though.
