Regarding nodes. Do you see a massive increase in people that get arrested for being a peer in the torrent network? Because I don't.
I see two basic possibilities:
1) Everything remains peaches and cream in fiat-land.
1R) Bitcoin serves no particularly useful role. Remains a minor sideshow which cannot compete successfully with Mastercard, PayPal, cash, etc because it does some fraction of what these things do for mainstream users only worse.
2) There is disruption in fiat-land.
2R) Bitcoin provides an accessible (unlike gold) means of wealth preservation for the non-politically-favored. In that case it will be attacked by the corp/gov state with no holds barred and some abstract ideas about 'freedom to use Bitcoin' will be among the last of the rights that people will be worried about having lost.
A non-defensible Bitcoin is something I haven't much interest in personally, but whatever floats your boat.
With respect to TOR, the govt doesn't need to outlaw it to kill it; ceasing to
fund it would probably be sufficient to accomplish this. One of the few places I agree with Hearn on is that some reliance on TOR is worth sacrificing much to achieve. If Bitcoin cannot feasibly run on some combination of a privately maintained and somewhat covert networks and steganographic methods on corporate owned networks, it can easily be degraded to the point of uselessness. And probably will be just in time for it's having some actually useful role in the world.
edit: added 'cash' to the list which is highly relevant in that context.
