So by the same token, I would guess natural immunity is also good?
If you're a fan of eugenics, perhaps. We already have 1000s a week being killed, and many more disabled, by it.
Add in the additional (non COVID) deaths due to delayed diagnosis and treatment....because hospitals are full of Covid patients and dead or off sick HCP. You'd better take care when going for a drive. You wouldn't want to risk an accident during a time of full hospitals...
And again. Long COVID. It is a thing. A rather worrying one for some. Linked to that, a while back studies showed that a sizeable minority of apparently recovered COVID patients died within the next 3-6 months after hospital discharge. Tended to be COVID related conditions (but of course as it was months later, the active infection was gone and tests were negative - and so COVID linked damage was recorded not as COVID death but instead as heart attack, stroke, pneumonia, sepsis, etc.)
How do you know you can get natural immunity from a new mutation btw? Different mutation and all that. And from a possibly semi unnatural virus that could have been modified in a lab (yes, I know it's just a possibility but it would be foolhardy to totally dismiss this when considering mitigations).
