You are right. But if things have changed, they can change again. Many countries are in the process of banning smart phones in schools and are legislating age minimums for social media. In such environments, access to social media becomes much less important. I think a better long-term approach would be to mitigate the risks of social media, and the fediverse is already addressing some of the big problems like corporate control of information and algorithmic curation of content. I like the idea of social media, but i hate the (prevalent) implementation.
