I think you're missing a piece. Lockdowns are mostly triggered to control the impact of COVID on hospitals.

If hospitals become overwhelmed by COVID cases, the impact is far beyond any additional COVID cases that can't then get treatment - it then spreads the impact to people with heart attacks, strokes, and many otheer acute life-threatening conditions. It also likely impacts care of people with cancer... and people with appointments for important elective surgery. And so on.

This seems to be a fundamental schism: between people who understand/acknowledge that our collective behaviour impacts many other people in direct and indirect ways, and people who are more focussed on individual autonomy and freedom - who maybe don't see (or care less about?) the subsequent impact of their actions on others.

This is how people choosing not to be vaccinated harms everyone else, and risks measures like lockdowns. Because there's a inverse correlation between vaccination and severity of COVID infections, it therefore follows that not being vaccinated (on a wider scale) increases the risk of hospitals being overwhelmed - and so increases the risk of lockdowns being necessary, and 'innocent' people with other conditions requiring hospital care being caught in the middle.
