I'll preface this reply with the information that my father was a doctor in the British Army during the Spanish 'flu epidemic. And in 1919 he caught Spanish flu himself; he was looked after in a military hospital isolation ward (in a tent in a field in France!). And he obviously recovered, but one result was that he did instil in me quite a bit about
matters of health.
The key thing with this, or any, pandemic is to prevent a health care system being swamped with too many patients that at the same time, or even more specifically, prevent too many patients that all require intensive specialist treatment arriving at the same time when there are not enough specialist treatment facilities to go round. (It’s basically a complex production line, where if one bit goes at the wrong speed, then it fails to make the product.)
If you have, say, 10,000 Intensive Care beds available per month, then you should be okay if those cases arrive at a rate of 10,000 per month every month (or better still if you get 8,000 cases per month so you always keep a bit of spare capacity). Of those cases, some will die and some will recover.
However if you get 8,000 in the first month, 16,000 in the second month then 32,000 in the third month, 64,000 in the fourth, etc (we’ve all seen the curves where the line gets steeper and steeper), then there is a very strong chance that ALL the cases for whom there is no IC bed will get too ill to have any chance of recovering and you could see ALL of them die. (6000, 22000 and 54000 for the numbers I mentioned above)
The paradox with the strict measures is that, if you get it right, then the system copes and you do not see a disaster, and people might ask what all the fuss was about
when it’s all over. (Like with the “millennium bug”: my computer did not crash because someone else designed the right software fixes to prevent the problems and my system was able to downloaded them to update my system.)
And believe me, being healthy, but stuck at home so you do not spread a nasty disease, is better than being isolated in a hospital because you’ve got it: as a kid aged 10 I was isolated after getting meningitis. Not good!

EDITED as, after I posted this and reread it I saw that I accidentally deleted the important sentence that said that the danger we are currently facing is due to the fact that unlike seasonal flu with Covid many more people end up needing Intensvie care treatment.
