Of course Bitcoin has it's benefits, but it benefits more for the people than the government and that's what Chinese government are getting rid of.
I can't agree more that the decentralisation of Bitcoin plays a huge role on why they put a total ban in crypto. However, China might not even after Bitcoin's benefit for now since they are very keen financially. They always find a way how to manipulate their people and even other nations financially.
A bit off topic, sorry. I don't fully agree with certain points of view, and I don't mean to change your opinion.
China has a history of humiliation, and maybe many countries have it. To some extent, we enjoy peace and stability, but we have to sacrifice some democracy and freedom. I believe this is understandable.
I agree that the Chinese government wants to know the ins and outs of the money. It's like the US has taken control of the Swift system. The U.S. government actually knows the inflow and outflow of every dollar. No offense. But if Bitcoin actually threatens the Swift system, my guess is that the U.S. will immediately ban Bitcoin from the world. Calm down. Because Bitcoin is not yet able to challenge the status of the US dollar.
In addition, the status of the US dollar and the RMB in the world is different. This is incomparable.
