There is a difference, whose significance seems to be lost on you, between peer-to-peer, voluntary communication and centralized, forced distribution.

You are not forced to read pamphlets nor do they insert the content of the pamphlets into your newspapers and letters. Typically the only thing you are forced to do by someone distributing pamphlets is to tell them whether you'd like to take one. If advertisements had to ask whether you wanted to see them, the entire industry would collapse.

Pamphlets are also not magically distributed to everyone. People have to decide to help distribute them, which means other people have to cooperate with you to help you spread your message. It is also easier for others to interfere in your efforts, as, unlike online, people can see who and where the information is coming from, and they can also more easily and directly inhibit distribution. On the other hand, any individual can buy a Facebook ad and, with enough money, shove it in millions of people's faces with little to no oversight. Hence, it is easier to spread misinformation (like anti-vaccine propaganda) through Facebook than in real life.

Online ads - and most ads tbh - don't force you to do that either. They want to attract your attention but you re free to ignore them. I used pamphlets as the equivalent of advertising in older times, i m sure people would consider them just as pushy/spammy back then as we consider online ads now. They are not peer-to-peer by definition - there is no point preaching to the choir.

You aren't free to ignore them. To even look at them to identify whether they are advertisements takes time. Even if it took a millisecond, with a billion people looking at it that's 12 days of man-hours lost on every advertisement.

Pamphlet distribution is peer-to-peer. People have to distribute them to other people. However, Advertising is usually lopsided: typically a group of people working together, like a magazine corporation, or a machine, like with Facebook, is distributing content to people. And again, receiving ads from these places is not voluntary. You cannot engage with the activity but refuse receiving advertisements, unlike my experience of walking around on university campuses and refusing pamphlets I am offered.
