Not very hard because a lot more info than an IP follows you. For example, in addition, a computer network ID also follows you, that will stay the same no matter the IP you are hitting through so patterns can easily be established even if you use an IP masking service or jump around on public or open networks. I've also seen set up situations where a cookie was deliberately placed on a computer via responding on a forum (not here).. That's just the amateur stuff.. the government is thousands of times more sophisticated in their approach.
Boy things are going downhill faster even than I thought it would. Hmmm maybe we need some sort of secret code???? During the Revolution Patriots used a code when exchanging messages back and forth the British were never able to crack.
I will find the links and show you about 20 felony cases where the FBI was unable to find the criminal by their IP. One was a hacker. I will search for them and post here to prove that you are incorrect.

Not if your computer protection doesn’t allow cookies. I have 3 programs, cookies are only allowed on the sites I choose. Others, no way. Get a cookie cleaner, run it every hour or so, deletes all cookies. Get spyware that runs constantly and blocks. Set it to the highest levels of security. Surf in stealth mode. Granted, some web pages won’t load but I don’t want them to if my programs detect things I don’t want.
