The point I think is one of delaying things "Letting it run its course" implies no action, which would be not correct. Herd immunity is desired but with change in the nature of the epidemic so that old people don't die as much as if they did nothing. Also herd immunity.is not 100%, you just need a certain high proportion. If you can protect those most at risk also then it could work.
