Self-Custody is problematic for any government as it allows any citizens to accumulate any kind of wealth they have and simply "transfer" it overseas without any oversight and in a ridiculously short amount of time. Some countries (rich/developed countries) allow free capital transfer but these transfers are regulated and also some jurisdictions are sanctioned. Transferring money abroad, from the perspective of the origin country, just moves the money inside the origin country system from one party to another. So it is well within the visibility and control of the state, especially for large amounts of money.

Today, you can brain-memorize $1bn in Bitcoin and move yourself from one country to another; and depending on the country; might be able to exercise different amounts of that purchasing power. Control moves from the origin country to the reception country.

Russia and China were always hostile because of this. The Chinese authorities regarded Bitcoin as some sort of capital flight scheme. Now both Europe and the USA are too. I think Bitcoin only chance for survival, in its current form, is if these two poles do use it as a mechanism to attack one another. Mining is already balanced between East and West.
