You have made a very good strong point which is very valid as political concerns has influenced Bitcoin in a way but you also need to understand that Bitcoin isn't here to replace Fiat, it is not here to take over the position of how the modern government does their finance but to be a tool for investment, a modern finance intermediary for cross border payments and also as a currency where it gets the chance to, there are also other functionalities that Bitcoin can always serve in, mostly for utility and so the battle here is and was never to replace Fiat and so there will be no need for any of such fears to be nursed, it is mostly for the individual ownership when it matters, that's why it is decentralized.
You write like a very long paragraph with only one sentence. Why don't use dot to stop and break your idea expression into sentences for more comfortable reading and interpreting meaning for forum users.
Political changes in China, the USA and around the world in many nations don't damage, change or destroy Bitcoin decentralization but surely policy changes as consequence of political issues, geopolitical conflicts or pure economic issues in one nation can affect Bitcoin adoption here and there.
Bitcoin was not created to replace traditional bank system or completely replace fiat currencies globally, in a more precise word, Bitcoin was created as another choice for people who love decentralization, no censorship, and self-control. Who like it can use it, who dislike it can ignore it, while governments can not make a death for Bitcoin or destroy its decentralization.
