In the U.K, the number of cancer patients suspected of dying because of interruption to treatment is about 3- 4000. The total number of deaths from covid is about 125 000 as of today.
In the U.S, since March 2020,there is a clear picture of excess deaths in the community, that is, an excess of people that died compared to normal.

I couldnt find any figures for the amount of cancer patients that have died because of interruptions to treatment in the U.S.
Pete, it sounds like you are making some assumptions about health. Many people have to deal with a variety of health problems through no fault of their own, including type 1 diabetes, hypertension and high cholesterol.
I think there is a point to be made about the collateral damage of covid restrictions but at the same time, I believe governments were preparing for the worst. The severity of the illness made some question the need for strict measures but who gets to make that decision- Facebook professors, or real scientists? Also, how much more severe would covid have to be before non-believers took it seriously- 10%, 30%? Who gets to make that decision?
Finally, people doing nothing and letting the virus spread increases the chance of it mutating into something far worse, that's the reason I personally felt restrictions and lock-downs made sense, if they were properly implemented and followed.
