Ahh ok good question I didn't really flesh that out.
>"Why do you think tor is going to 'inevitably win'?"
Not just tor, but p2p in general. Basically the theory is that, as a species, we're used to few-source/many-sink communications networks.
We've been using them from the printing-press all the way up to DVDs. The internet & its "many-source" capabilities represents a threat to the prior (and existing) information-source monopolies...such as any media industries, national-banks, or governments.
A great way not completely lose control of information dissemination is to control the paths information must take.
Two great examples of threatening p2p protocols are Tor and the distributed bitcoin-ledger. Taken in conjunction with "criminal activity" historically being the way to demonize most cutting-edge tech when it challenges the status-quo, and a pattern starts to present itself.
To answer your question: I think our regulators are being reactionary Luddites & that p2p is sort of the spirit of what's driving this whole internet-thing...otherwise it would be interactive television.
