I would argue that if there's a product that nobody knows exist that's not necessarily because we need to allow constant intrusive ads, and more indicative that people don't actually need the product.

I want to say that in any given day, 60% of the ads I see are from big, well known companies who don't need me to see them to know they exist. Shit like Liberty Mutual (I swear I see more of their ads than anyone else and THEY ARE ALREADY MY INSURANCE PROVIDER), Coke, Pepsi, etc. 39.9% of the remaining 40% are advertisements for shit that I just don't care about. I don't care about the newest tech toys. I don't care about the newest car mods, or random shit I can put on my desk, or stupid extra kitchen gadgets. Fully 40% of the ads I see are trying to convince me that I should buy a product that I straight up don't need because the ad looked cool. Why should those ads be allowed to exist? Why should I be constantly bombarded with ads for services that I either already know plenty about or for things that are trying to manufacture a reason for their existence?

Only about 0.5% of the ads I see are actually for things I did know know about and that seem useful to me, or like something I would like. Probably even less than that, I'm drunk rn and estimating.
