an IP is just an IP.
just because you think Tor or proxies are the only way to change/mask/borrow an IP. is again nothing to do with the bitcoin protocol. but more to do with human choice and human knowledge.
there are many many other ways to separate yourself so your real life info is not linked to bitcoin transactions. this is not a fault of bitcoin. this is again human choice
Yes there are other ways to obtain an IP that is untraceable to your identity such as an unregistered prepaid USB dongle, connecting through an unregistered WiFi connection, even using a botnet to get throw away IP addresses.
But mining pools need to be at a stable IP address so none of those options above apply.
Also you did not address the point I made about Bitcoin's protocol can't provide untraceability and unlinkability.
The relevant analogy is you are the
Philosopher's stone who can make gold with alchemy. Although it might be possible, it isn't practical nor realizable.
I do agree with the underlying point of your thesis, which is that the more the government pushes, the more we will push back. So they would be wise not to regulate mining too soon. Wait and do it when they are really ready to take control so we don't have enough time to push back. Given your "don't worry" Philosopher's stone attitude, if they are wise and don't alert us, then we won't be able to implement fast enough once they go into rapid fire action around say 2017 or so.
