How can country fund social programs during crisis like COVID with Bitcoin standard?

I am obsessed with Bitcoin and trying to learn as much as possible. The countries around the world printing money to provide stimulus checks to the people who lost job during COVID. If countries adapts Bitcoin standard then they can’t print the money during the crisis.

In this case, how the government can supports their people during crisis? Do they have to have Bitcoin in their reserves to use in emergencies? What if they don’t have enough Bitcoin?
