You are unlikely to see anything like that number of deaths from Covid before herd immunity kicks in, ff. For a start those deemed to be vulnerable would mainly opt to stay out of it. And it'd be the government's responsibility to ensure old folks' homes aren't being dumped on. Furthermore one has to get to HI at some point, all that's presently happening is it's being stretched out to take longer getting there; and, not that it's a relevant argument either way, but the reality is that in a population of 66,650,000 100,000 is 0.15%. And compare that to heart disease that kills 170,000 a year.
