My point was that some "bad guys" aren't using encrypted communication at any cost; they're using encrypted communication that's easy enough to use. If you made encryption a bit harder to use (say, by taking away Signal), some percentage of existing "bad guys" would no longer use it. (To be clear, I don't think this is a reasonable argument for banning Signal; I just wanted to make the point that laws do affect the prevalence of encrypted communication even among criminals.)
