You should get worried about it, because in my opinion this is just beginning it is very possible that in the future governments approve laws in which it is required to identify yourself every time you make a transaction in a blockchain and if merchants begin to cooperate with the authorities then is possible that bitcoin could get adopted worldwide but we will lose any kind of anonymity while we are using it, in my opinion that it will be a very hollow victory for bitcoin, if we want to change the way the world works bitcoin needs to remain as it this and not to become another arm of the government.
Valid concern for sure. In current times with regulations becoming more and more a normal thing, the centralization aspect fiercely starts overruling everything we care about. Bitcoin becoming mainstream has definitely two sides to it, where the price keeps increasing as result of that, which everyone rightfully considers to be a positive development, but we also more and more lose grip of what we do and how we operate. It's impossible to achieve something without sacrificing anything. No pain no gain they say, and I agree with that. Good thing however is that if we so wish, we can still avoid dealing with the regulations the centralized ecosystem is subject to. If we at some point manage to create local crypto economies within each country, we don't have to deal with fiat, and thus don't have to deal with a large part of the regulations. It needs a mindset change globally, but it isn't impossible.
