You are right, a p2p web wont solve the barrier to entry, but web hosting costs $20 a year, so its not much of a barrier.

The real cost is scale, $20 year will cover a few thousand users but if you want googles scale it will cost you in bandwidth and complexity. p2p like torrents radically reduces the cost of bandwidth by distributing it, but more importantly it reduces complexity by standardising it.

Once the complexity is standardised budget web hosting can provide google scale for dirt cheap, and there are millions of budget hosting companies too many to shutdown them all giving you censorship resistance.
