OP, I understand what you're saying and what the supposed promise of decentralized everything holds for the internet, but I'm cynical.  In fact, whatever it is that's two steps beyond cynical is what I am, so the way I see it is that if something can be improved upon or innovated with respect to the internet, big corporations and/or governments will find a way to fuck it all up.

Napster and all of the P2P file-sharing programs that came after it were extremely popular for years until that handful of people got letters in the mail telling them they were getting sued for illegally downloading music.  That made the news, scared people off, and although there's still massive piracy going on it shows you that just because something is decentralized doesn't mean it's outside of someone's control.

I've heard it said here many times that bitcoin can't be shut down by any government.  That might technically be true, but it certainly could be made illegal--and then you'd be a criminal if you stayed in the bitcoin space.

And lastly, I remember all the hype about web 2.0, which was all about user-created content....and what did we get?  A bunch of idiot Youtubers conforming to Youtube's policies and their sponsors' demands, all trying to sell you something.  There's more advertising in a 12-minute video than you'd see in an hour long TV show, and the "content" is made by total amateurs, no matter how good the production value is.  Ugh.
