Last time I checked, a product label (on the product or on the package) is not an advertisement. It's just the name of the product and/or brand, and maybe some lines about what it does. Even if you call a product label "a sort of an advertisment" it's fine.
When people complain about advertising today, do they refer to product labels? Or to their friends telling them about a product? If not, why are you bringing this up?
>Am I allowed to tell my friends I like a product? What if I put a video on youtube and accidentally include a brand name in it?
Sure, as long as you aren't getting paid for doing it (directly or via affiliate kickbacks). If you are, and you're discovered, you pay a fine - or go to jail.
You try to paint a "it's impossible" all or nothing scenario around marginal advertising and edge cases. Doesn't matter. If we can get rid of 90% of overt advertising - tv ads, streaming ads, posters, billboads, radio jingles, that's enough, even if "you put a video on youtube and accidentally include a brand name in it".
