Then how does herd immunity stop most of these deaths? Because you made an absolutely ridiculous claim that only a few thousand people would die if they were exposed to the virus.
You've been around and around saying things that seem to not be very important for your argument, trying to claim that herd immunity is all important, now you seem to be saying it's not very important at all.
Its very simple.
Herd immunity is what normally ends all epidemics, including seasonal flu, measles, polio, etc.
The way herd immunity works is that the virus can only survive 12 days in any particular human host, and if it can't infect another in that time, it is gone.
So the initial spike is what normally kills off any epidemic.
It uses up too many of the easy local hosts, so then can't find anyone to transfer to, and dies.
So why didn't this happen with covid last March?
Because we deliberately prevented the initial spike.
Instead we used masks and social distancing to "flatten the curve", which essentially conserves hosts, so that the epidemic never runs out of easy hosts.
How does killing more save lives?
Because the initial spike would have been twice as many that month.
A normal spike would have killed as many as 60,000 people in one month, but then be over and done with, gone.
When you "flatten the curve", you reduce the death toll to only 30,000 instead of 60,000. but you ensure it will keep infecting others, month after month, essentially forever.
It is actually a little more complicated than that because I would have greatly reduced the death toll way below 60,000 even.
Go back to Fauci's estimate on herd immunity, and you see he posed 2.4 million would die.
That is 2% lethality of the 70% of 330 million, you need to gain herd immunity.
That is already too high because he ignored the asymptomatic, who not only mean about half the population started out already immune, but also that his lethality figure was at least double what it really is.
But the main reason Fauci's number is off is that he was assuming you do not select who gets infected, and wait for the vulnerable to just die.
And that is not how you end an epidemic properly.
Instead you use variolation.
{... Variolation was the method of inoculation first used to immunize individuals against an epidemic (Variola) with material taken from a patient or a recently variolated individual, in the hope that a mild, but protective, infection would result. ...}
The point being that if you deliberately infect the young/healthy, then you reduce the death rate by a factor of 400.
Take Fauci's 2.4 million death from random infection spread, and reduce by 400 if you confine it to only those under 40 and healthy, and you only get 6,000 deaths as a final result.
