Yes, if you crush your computer into a cube you won't see ads again either. But people want to keep their computers and block content they don't like, so there's "problems to solve" there.

The problem of not disabling JavaScript and not seeing ads. I.e. granting users control over the code their browser runs that's finer-grained than "nuke it from orbit".

I just disconnected my computer from the internet. I don't get any ads at all, now!
