My idea with second question was to understand if there is like an anarchist motivation around bitcoin that may have some risks in the future.

Ok, I think I see what you're getting at. First of all, crypto-anarchy is very different from plain anarchy. We (or at least I) weren't trying to destroy government, but just create new virtual communities that aren't ruled by the threat of violence. Second I'm not sure Satoshi would even consider himself a crypto-anarchist. I think he might have been motivated more by a distrust of financial institutions and government monetary authorities and wanted to create a monetary system that didn't have to depend on such trust. All in all, I don't think there is much risk in this regard.

You say you don't think it was Szabo. Have you ever try to know who he was? Could you share who is your solid hunch and why?

I haven't personally made any attempts to find out who he is, nor do I have any idea how. My guess is that he's not anyone who was previously active in the academic cryptography or cypherpunks communities, because otherwise he probably would have been identified by now based on his writing and coding styles.

Is relevant to know Satoshi?

I think at this point it doesn't matter too much, except to satisfy people's curiosity.

If you know what you know today, would you have patented bmoney? Do you think bitcoin inventers would have done the same?

No, because along with a number of other reasons not to patent it, the whole point of b-money was to have a money system that governments can't control or shut down by force, so how would I be able to enforce the patent? I don't think Satoshi would have patented his ideas either, because I think he is not motivated mainly to personally make money, but to change the world and to solve an interesting technical problem. Otherwise he would have sold at least some of his mined Bitcoins in order to spend or to diversify into other investments.
