When you're debating the merits of the law in question, it doesn't seem like a valid defense to say "if they can't do business under the law then that's their fault".
If I say "car dealers can't sell cars that go faster than 10mph and if they go out of business then they shouldn't exist", it's clearly fallacious, and I don't see how this is any different.
