Sorry to burst your bubble(hehe), but it's really pretty much impossible for bitcoin to have no government regulations. Heck, I can almost guarantee it that more countries are going to ban bitcoin(probably temporarily) once they feel threatened enough by bitcoin. Probably a better and more realistic sort of "dream" would be for the governments to declare bitcoin as legal tender, and to implement sort of "fair" tax laws concerning bitcoin and cryptocurrencies. Yea taxes suck, but let's be real here. They're going to make money off the taxes as much as they can.
And people do really need the guidance of the government. I wonder what will happen in the future if there will be no banking institution, it will decrease the jobs available for the people. In such a case that they need to find jobs in cryptocurrency which is quite hard if they are focused on regulating fiat money especially those that are tangible. For me, we need to balance cryptocurrency and fiats, not literally to transition crypto as a replacement to fiats in which in the first place fuelled our economy.
who know ? what if they changed thier minds in the future ? but i dont believe that banking will vanished . if bitcoin replaces fiats bitcoin banks will also appear . if bitcoin is dominating , bitcoin jobs will also be available for all of us but at the end of the day all of these were still a dream for now . i also believe that bitcoin and fiats will be working together and helping each other , not to compete or fight for each other and governments are going to be in the middle .
