That's correct. We stop everything for 3 months to get rid of the virus.
Or almost everything.
> almost all home and commercial property sales stop
Have you tried buying or selling a house these days? In most parts of America, you can't -- the registries of deeds aren't open for business with coronavirus. This is already stopped.
> What you are looking for is the time equivalent of printing money
It is like a time-equivalent of printing money. By virtue of the time-limit, it doesn't have nearly the same inflationary pressure. We need to relieve a short-term financial crunch, and the stimulus, zero interest, etc. all do that, but when the crunch is over, that stuff explodes into inflation. This cleans itself nicely.
> It's too simple of an idea
What's wrong with simple ideas?
You don't actually need to immediately record the deed to buy/sell real estate. I believe this used to be the norm back when remote towns would batch up all their new deeds and send them to the county seat by horse.
Or are we also expecting that grocery stores provide food on credit that they are not expected to collect on any time soon?
It's too simple of an idea. What you are looking for is the time equivalent of printing money. Right now that's magical, it's a deus ex machina event. It's implausible. You have to innovate it, and until then it's a fantasy.
