Bitcoin is a protocol which has evolved over time to meet the needs of its users. In the next decade or so, Bitcoin will have a soft fork to deal with the problem of quantum computers.

Even if a state actor manages to break the asymmetric cryptography before then (literally impossible to get enough compute power to do this currently), the users can just fork the blockchain before that happens, fix the bug, and continue on.

Every single financial system that currently exists has a big potential problem if someone breaks asymmetric encryption. Every single government power also has a very big problem as well.

Almost every entity in the world has an incentive to find the solution to this problem, and when it is found Bitcoin will just do a soft fork and include it into itself.
