> they can’t(?) blacklist people from using the tokens that come out the other end. why not?

  Because defi exchanges are also smart contracts. Unless you have an automated system that watches all tokens coming out of tornado and then immediately modifies the the exchange smart contracts to blacklist them it’s not feasible.

    If exchange cant block such transfers, then it is possible that exchanges cannot operate legally. Maybe locking account of user who use it will be sufficient.

    I'm sure the smart contact language is powerful enough to specify that tokens from Tornado Cash will not be handled. You talk about it in terms of self-modifying code but that should not be necessary. That tokens from "something like" Tornado should not be handled, though, seems like it would be harder to specify.
