If you have no background in either field involved, how on earth do you know you're not underestimating anything man? Now, I'm no doctor or medical expert, but I do have a civil engineering degree and experience, and building hospitals isn't something that's just super-duper snap-your-fingers-and-it's-done-overnight easy by any stretch of the imagination. Not to mention ventilators and other equipment needed to treat severe cases, the PPE needed for medical staff, and, of course, the sheer number of doctors and nurses that would be needed if things get as bad as they could if we just continued life as normal with no social distancing or quarantines.
(edit: the whole idea is to slow the spread of the virus, that way we don't overwhelm our capacity to treat people. This capacity depend on hospital capacity, medicine, equipment, staff, etc. If a s**t-ton of people all get it at once, it's much worse than if the same number of people get it over a much longer period of time)
Frankly, you're speaking out of your ass... "if they can't, too bad." If they can't, then it won't get done, and millions of people will die. If that's "too bad" for you, **** right off...
No, a quarantine can't go on forever, but your "solution" is nothing more than the wishful thinking of someone ignorant in the fields in which they are speaking...
(edit: I also love how you're stating what is the "wisest strategy" despite making no sense at all, and citing no sources. Yeah, you're the wisest...
