To acquire immunity while there are still hospital beds available in some places, in the unlikely event that you need one. That won't be the case a month from now.
If instead, we all stay home and quarantine, the second we start reducing the quarantine the virus flares back up again. If instead, we start acquiring immunity in low-risk populations, at a rate that the hospitals can sustain, we'll have a degree of herd immunity and a portion of the population that can no longer spread it.
I'm certainly not an epidemiologist though; anyone smarter than me that can way in on that thinking?
A fair portion of low-risk people will require intervention. Given that a lot more people are low than high risk, you're still overwhelming the health system, and all those low-risk people are still going to interact with others while they are asymptomatic but transmissible.
Time means more ICUs, more ventilators. It means industrial capacity can shift from making consumer goods to medical supplies like masks. It means medical personnel get training and experience with the disease instead of shooting in the dark. It means labs and research teams can give more informed treatment advice.
It means small businesses and industries can try to reallocate resources and jobs and maybe save part of the economy. It means more time to educate the population to avoid high risk activities, wear masks, wash hands and so forth.
In every way it’s better if we delay the pandemic now that we know about it than if we just let it peak exponentially and kill the maximum number of people.
1) Such an individual would be contracting an unknown virus in an environment where hospital staff are the least prepared and practiced at dealing with it.
2) Such an individual is still exposing themselves to high risk of mistiming the outbreak and hitting it at the peak.
3) They might accidentally catch a different disease thinking it is COVID. Then if they got COVID they'd have 2 diseases; which is probably going to be quite bad.
If we all avoid getting COVID-19 for, say, another 2 months it is likely we'll have an available and effective drug for treating it. There are something like 5 different candidates I've heard of, so even if the odds of any individual one working out are <30% there is still a good chance there will be effective treatment by mid year. The contain, delay and avoid strategy really is a better bet.
I don't believe this is likely at all. At best we will have something that kinda sorta works in some patients. If this was likely we'd have a drug for the common flu long time ago. To remind you, the flu takes about 50K lives in the US every year.
