Regulations can only affect pace of adoption in that country. But bigger problem for them is if citizens don't buy it. Imagine this like a digital gold which everyone can go into digital world and take it. However your country don't let you go get the gold and because of their stupid laws you will have to buy the gold from us who took it now for much higher price. That government and their citizens would be left behind in new world order. This is the reason why no country banning crypto. They are just trying to get taxes and control pace in the process.
