P2P enforcement forced anonymity and evasion technologies to evolve far faster than they ever would have if the FBI had been the only 'threat' to privacy online.

I agree with this conclusion. You don't really want mostly innocent people resorting to these technologies. Pressures such as RIAA enforcement have helped create these networks, and ISP Data Retention as well as laptop border searches will push it further along. If you are creating a policy situation where most people fear monitoring and prosecution you've done something wrong.
