Then thats why bitcoin is a good thing. No one individual or group has control over it, and if it were adopted by a state it would have enough mining power to eclipse whatever 51% attack a state might attempt.

The only thing a state could do is try to outlaw transacting with individual addresses, which is only as effective as trying to tell people not to do in person transactions with them. I guess the downside is that you can trace all payments, but with bitcoin you can easily generate new addresses and pad your money path to obscure who you are.
