> Any sort of aggregated comparison of places to purchase from can be considered advertising

This is where your confusion stems from, I think. Any sort of independent third-party review site is totally not advertising as far as I'm concerned. The problem with sites like Yelp is that they accept money from companies and are susceptible to astroturfing. But truly independent reviewers like Consumer Reports, are pretty clear not advertising.

> Now, on that site, is this company allowed to advertise different brands that they carry to me? By definition of advertising, no - the whole purpose of showing me products is to make me purchase, which is the definition. So then do we reach a true communist state where there is only one option to purchase? If so, can I still not see it because it's considered advertising? Okay, fine, I need to be able to see at least one guitar, we can concede that point.

This seems like handwringing about the most extreme possible form of legislation possible which nobody is proposing. I am not sure what definition of "advertising" you're thinking of, but having a list of what products your store sells isn't advertising by any reasonable definition.
