The nature of BTC still is decentralize, it hasn't changed but then we are now regulated because of the illegal use of cryptocurrencies. You can't expect the government no to intervene because if its not going to be controlled, more will probably scammed. We saw these happened when in 2017 and were just jumping out after the bullrun.
P2P still offers decentralization and some coins are pretty much unregulated still. If you are onto that, you should move on into those privacy coins.
I agree, but the problem with government regulation in general is that they don't have to answer to anyone. Some amount of regulation is generally good but who draws the line? The people who benefit from it. Banks. All kinds of institutions connected to governments. And these institutions don't want regulations to be good for people, they want regulations to be good for themselves. But this is no secret, everyone knows how these things work. That's why someone tried to create technology layer to prevent it. But technology alone can't do this. I guess our only option is to educate people. Because so far people don't care what the government is doing as long as they have enough to bring the food on the table.
