I'd be willing to pay slightly more in postage in order to eliminate junk mail. The mob (or patent troll industry or insert random undesirables) employs people, too, but you wouldn't argue for its protection solely on that basis. And the fact that it works ignores the fact that it irritates everyone who isn't a junk mailer. There are far more honest ways to advertise.
Not sure what you're trying to say here.
