It's not illusion. Yes, govs can make an ifluence on BTC, ban it or support and that will make BTC go up or down. But it's not directly controlled by anyone and can't be totally shutten down.
correct, they can influence bitcoin only but they don't have enough power to shut it down as its decentralised, i don't know why there's a bunch of people who still really claiming that bitcoin isn't decentralised wherein despite it's very obvious tho. In fact if government had an access in bitcoin for sure it's now fully down and there's no improvement in it. But see what always happen, bitcoin is totally free in the market there's a problem only when manipulation occur.
