The legalization of bitcoin does not necessarily lead to a better economy for a country, if the government is not good at issuing a law for bitcoin, it may actually be a huge disadvantage to them, since bitcoin allows its users to take undercover transactions and possibly harm the state. I dont really think that bitcoin can do that for us or the country itself. Thats bazaar idea to think about as the constructions or amenities that you have mentioned here are handled by the government
