There's legislation being discussed as we speak that may deal with many of these things, even if only on a temporary basis. It's simply false that the only things we can do, we must do as individuals and cannot do through government and with political leadership.
If you're making a narrower point about Medicare for All, I'd put that in a different category than most of these political recommendations simply because it would take years to implement. But that's different from arguing that we should ignore the merits of sound public health recommendations on the basis that some people have an ideological aversion to hearing it.

I'm arguing that any such attempt is doomed to failure if it so much as even stirs the beast of partisanship because of how far gone our civic discourse is. I believe most or all of the things you listed can be done quickly by the executive branches of local, state, and federal governments within the bounds of existing legislation. At this point, anything but the most bipartisan bills are impossible to do on a short time frame. The place to be is lobbying governors, political appointees that lead state and federal agencies, and civil servants on the ground. They have unilateral power to actually do something about the situation because emergency powers are very broad (Lincoln used his to suspend habeas corpus!) and justices will be even more hesitant to reign in executive power during a pandemic than whatever immigration state of emergency enabled the travel bans. That way, even judicial branch challenges will slow down partisan interference instead of obstructing the intended goal.
I hope I'm wrong and our legislature does pull it together under threat of an emergency. After all, if JFK getting shut down was enough to end the government shutdown, maybe a pandemic cratering the global economy is more than enough to bring us together, at least for a little bit. However if the goal is to get something done instead of arguing over what to do, I'd look to the executive branch, not legislative. The former is meant to do, the latter is meant to argue.
Edit: I wasn't trying to make a point with medicare for all, just trying to pick out some examples from different sides of the isle (single payer on the left, free market reforms on the right). I'll admit I don't know enough about either group of ideologies to predict which relevant bills would be bipartisan enough to pass quickly but based on how antagonistic partisans have become, I don't think it'd be much since we don't have much time for the normal pork barreling process to work.
