In Japan bicycles are regulated. Each has to have a unique ID registered to the owner's name and address. All to stop crime, of course 🙄

So that confirms my claims that the State would actually regulate bicycles if they could, but goes against my thesis because I imagine bicycles are more common in Japan than in the average of countries, so I would imagine it would be easier to acquire and much harder to track.
On the other hand it does tell us that Bitcoin could go either way and we should not assume one or the other.
