It doesn't seem true to me. Pretty much everything worthwhile on the web is gratis (nonprofits, academia, governments, hobbyists, etc.) or paid. The ad supported stuff is basically mainstream news, social media, youtube, and SEO spam sites. The overwhelming majority is less than worthless.

I think YouTube and maybe online banking are the only things I would actually miss.

Online banking is a service you pay for, not ad funded. I suspect if youtube disappeared tomorrow, peertube might become more popular for hobbies. Maybe the more entertainment focused professionals would find a way to make money, or maybe people would realize that if they're going to pay for entertainment, they expect something more like netflix.
