You're assuming that platforms that tried age verification in order to show people targeted ads would lose enough users to make that business model no longer viable. While I would fervently like to believe that's true, I'm not so sure it is. I think there might well be enough people who will hand over their personal identifying info without a second thought in order to continue to use targeted ad-supported platforms, to keep them in business. I hope I'm wrong.
