That's not how I remember it - governments locked down to prevent health systems collapse while a vaccine was created, tested and scaled for mass production. After successful vaccine deployment restrictions were lifted.
"health system collapse" was the inevitable outcome of any other approach to dealing with Covid.
"health system collapse" is worse than all of the other present and future side-effects, including the effects of denying healthcare to huge numbers of people over the past 2.5 years.
"health system collapse" didn't happen anyway. At least where I am (UK), it's increasingly clear that our response to Covid has blown open all of the existing cracks, and it's hard to say that we "saved" the NHS.
