Thats a very contradictory acceptance of the bitcoin if it were to be accepted in regulatory environment without compromising its decentralised nature. See, a decentralised environment is what giving the bitcoin real nature of it, and thats why it is being used for all the activities that are being done these days. For example, freely being played over the trades, gambling, dice games etc. But once the regulations starting coming up then they will surely intervene with the use of bitcoin in terms of above games, and investments. The same way they do it for the stocks and exchanges etc. I guess it wont be really good move and I guess that is why Satoshi made it like that way in the first place.
