"It has become clear to be that the internet is naturally monopolistic in a way physical institutions are not. One simply cannot move their gun channel, or the cigar trading forum to other sites and have a decent chance of maintaining even 10% of their customers."

That's funny - I thought that exactly the opposite was true.

The Internet (not particular sites, not AOL or "the facebook", but The Internet) is naturally un-monopolistic because you can, in fact, just move your video channel to your own website and do whatever you'd like there.

In fact, it's trivially easy to do so - you can probably accomplish the entire task using only your telephone.

If you feel that this is not the case I think you've made yourself fragile to services and processes that have nothing to do with The Internet.
