re: Setting a Dangerous Precendent

It's precedent, but hardly dangerous. Through this, we'll have better infrastructure and knowledge to handle it next time. And social distancing will save lives.
And there will be some permanence in the social distancing. There will be more remote workers going forward; firms will determine that they can get by with fewer workers. The change will be painful, but it was coming anyway and will come harder with AI (this was just the spark). Society will have to adapt. There will be "socialism" of some sort- of course there has been for years, it's just that when the handouts go to businesses it isn't called socialism.
But most of all, we need a beneficial supply shock, that can only come form technological advancement: like the PC of the 80s, and the internet and cellular technology of the 90s and 00s.
