There's nothing preventing you from setting up a web server, downloading free software to run it, getting your friends to view it, building encrypted communication apps that no government can crack, pirating any piece of content in the world, etc...
A libertarian society won't coddle you, and there's psychopaths like Meta who show up in the space and convince a lot of people to follow them. Of course those people suck, but the solution isn't government. It's to stay strong, help your friends be strong, and accept that not everyone will make it. That has always been the flip side of freedom.
The Internet, and now AI, delivered so many of the dreams of my childhood. It is a mostly free society, for better or worse. I'm hoping that intelligence remains distributed, enshittification stops when my agent deals with it for me, and the physical world remains as free as it is. But these aren't things that would be changed with new governance of cyberspace, these are features of the optimization landscape of reality and technological progress.
Do we live in the best possible world, of course not. But this one is pretty good, and it's easy to imagine non libertarian ones that are so much worse. I feel a huge debt to the people who designed the Internet with the foresight that they did, the capture exists at a psychological layer, not a physical one.
