The point of a social network, or blogging or whatever is that it's for others. Furthermore, I think people have the right to free speech and should have the ability to reasonably address the public square (for example, with a blog, or a forum or something).
What I'm saying in the previous comment is that regulations requiring "Age checks, encryption backdoors and other bad/annoying stuff" also apply to small hosts and can be abused like DMCA (unless you are hosting on tor/i2p with good opsec).
It's this notion that any regulation is good because it's done on a "big bad public company" that is at the heart of what I disagree with. At what point do you become a "big bad company"? Does anna's archive count? they accept donations. It just doesn't seem like a fleshed-out worldview.
