“The government” in the US certainly doesn’t have the authority to do most of these things.
Both the federal and state governments have vast powers during public health emergencies. For instance, the Supreme Court has made clear that the government can hold you down and vaccinate you against your will. Likewise, the Army (not just National Guard) can be deployed to enforce laws, including curfew and other quarantine laws.
Yes, it’s unclear whether government officials would be willing to use these options, and how much the public would resist them, but the formal authority is definitely there.
