You mean how do I find cinemas that are local to me? (Or streaming services, I guess). Again, pull. Search engines. Various categories of information broker.

What I'm pushing back against is the idea that advertising is necessary for society to function. I'm defining advertising in the broadest sense I can for the purposes of the thought experiment - information that you pay to have put in front of people. It can be entirely replaced by information that I pay to access.

It always will exist of course, because the incentives of a seller aren't aligned with mine, but it isn't necessary.
