Tubey you are arguing for COVID to become endemic. There’s no reason why it should, and it being endemic here causes many problems beyond just hospitalisations and deaths (and it absolutely would still kill people).
Of course it will be. We have several coronavirus strains endemic in the UK. It's unavoidable. Its too widespread, too contagious to not be endemic.
The alternative is never returning to anything like normal life. Which again, of this isn't killing or seriously harming tens of thousands of people, would be bonkers.
You aren't taking into account how the world works beyond COVID. The mantra "we need to learn to live with it" exists for a reason - because we do.
