@Synchonice is not wrong. If governments and financial institutions have their way they will own it instead of destroy it because underneath all those disguises they know what Bitcoin really is and what it could still be and they're too greedy to destroy something like that. But since they can't own it and control it the best course of action is to fight it.

But just like you pointed out, no single government can claim it even if an entity could claim ownership of Bitcoin (I don't know how possible that is). Everybody wants it. China wants it, The U.S. wants it, Europe wants it, and the biggest banks and other financial institutions want it, so who is going to be in control of it and own it since they can't all own and control it?
They're so busy fighting each other on relatively smaller things, what do we think will happen when they all try to acquire something as grande as Bitcoin?
