I suppose that's the attraction of El Salvador. they have nothing to lose from making it currency, and in the process just provided a lot of regulatory clarity. For all those builders who want to make something without waiting for more clarity for the US, it makes sense to move already. 

How robust is their legal system for continuing the clarity. Will the US continue to have the best legal system for administering abstract property rights. Or do supreme court justices get threatened here or there.
