Surely you can argue it is a fundamental right to have communication between consenting adults. But often in the case of advertising, the receiving party does not really have a choice. I would sooner argue that it should be a fundamental right to not be on the receiving end of communications you don't want, than that it should be a fundamental right to advertise to people who do not want to be advertised to.

I can't think of a situation where that's true.

This is my key argument on why billboards and similar advertising that can’t be avoided if you’re in public shouldn’t be allowed. There’s been no consent obtained.
