It's a tough one. Most of what governments do are bad. However, there are laws that are reasonable, like murder/rape/theft/etc being illegal. For those, the state violence, perhaps, could be considered like a mandated 3rd party defense against violence. I'm not sure what I think about the forced acceptance of Bitcoin. Perhaps on can argue there's some kind of higher force being acted upon the citizens of El Salvador, via the IMF and US that make vendors accept dollars. In which case, forcing them to accept Bitcoin isn't that bad. They sort of made a concession. They can't get rid of their dollar base because the repercussions of that would be severe, but just adding Bitcoin as legal tender, seems kind of minor to me. Ideally, people can use whatever currency they choose, but that's not where the world is.
