>No one is calling for the criminalization of door-to-door sales

Ok, I am, right now.

It seems like there are two sides here that are talking past one another: "people will do X and you accept it if you do not actively prevent it, if you can" and "X is bad behavior that should be stopped and shouldn't be the burden of individuals to stop". As someone who leans to the latter, the former just sounds like restating the problem being complained about.
