Earlier quoted context omitted.
Preparing to stay at home is reasonable. Expecting for no stores to be open isn't - even in Wuhan, stores have been open and selling essential goods.
Riddle me this one: If EVERYONE stays home, how do stores remain open? Do we think they are run by robots? I try to use language with some degree of precision. I said "assume no stores will be open during that time". ASSUME, not "stores will definitely be closed during that time". Assume, as a part of planning, not categorically know, because the assumption will make for better planning. It is far safer to make this…
But when people are reacting to the coronavirus, the implicit question isn't what preparations are good to have for general worst case scenarios; it's which preparations you're likely to need, which ones you can no longer afford to be without. As many a doomsday prepper will attest, there's always one more contingency you could plan for, but telling people to start with extreme measures makes it less likely they'll plan at all.
