I believe that there are some that will not want to agree. Bitcoin can definitely exist without Government support as we have even seen over the years in most regions but once we start to look at Global adoption then I too believe the Government is important on that note. Look at what happened today with the sharp drop in Bitcoins price because of the talk about SEC's investigation into Binance and possibly the upcoming Crypto bill set to be introduced tomorrow. So we can see that the Government still has their influence on crypto generally so their backing for Bitcoin mass adoption.
This is true that we need to actually have some sort of government support in order to keep it going with a high adoption rate. This is why we should not be really refraining to the point that we dislike government intervention. If we do that then we are not going to end up with any support at all and then all the crypto adoption would have to be on the behind the closed doors type.
So, in order to make this work, we need to pressure the politicians we elect to vote for crypto to be legal and also not have any high regulations neither, make it relaxed and taxed very little so that everyone would be able to invest into crypto without fear.
