If tomorrow (please take a second to imagine) that ads were banned and it worked (effectively 0 ads anywhere) I would still read journals that review new boardgames, I would still need products to fix my bike, etc.
It's value that makes capitalism run, not ads.
If there were restrictions on advertising that applied to everyone, then everyone would be on the same playing field re: getting the word out. We could argue all day about what the rules should be, but I don’t think anyone could argue against the point that we have clearly gone too far in the wrong direction and need more restrictions currently. We have an ongoing arms race between people using adblockers and Google trying to mass-break them now.
Last I looked in to the numbers I think something like 30% of the US population uses an ad blocker of some sort, that’s how bad it’s gotten. Browsing the Internet without even a basic one is so unbelievably painful and the data they collect/sell has gotten out of control. That’s not “advertising the business,” that’s a second revenue stream unrelated to the core product and done at my expense.
