Re: The safer each individual is, the safer the whole population becomes
Ok, so nothing makes you completely safe (not even the vaccine, that I remember being told would give 95% protection against serious illness) - but surely a balance has to be struck somewhere?
There is danger in all aspects of life, and it may well be that humanity is doomed anyway - if our population keeps growing then something will come and get us in the end, be it war, famine, other kinds of pestilence etc. Or just plain old Death: If I am covid-positive but have no symptoms, and I am hit by a bus, then I would still count as a covid death. I think that quirk of the reporting may be behind some of the recent claims that "omicron killed more people than delta" for example.
If 50% of the population have covid then (approximately) 50% of all deaths will be covid deaths, even if nobody died from covid. And this is especially true if (even non-deadly or vaccine-protected variants of) covid is present in places where people usually go to die, such as hospitals and care homes.
I think your arguments (that we should all be as safe as we possibly can be) are very similar to those around Nuclear Power. It is not possible to reduce the risk to zero, but if we double or treble the time and cost of each plant by mandating hyper-redundant safety systems, core-poisoning shutdown systems etc, (or by banning new builds altogether and/or closing existing ones) then we can marginally reduce the safety risk.
After all that, we find that other things have killed us, i.e. carbon emissions, particulates, and, ironically, airborne radioactivity, from burning coal and oil.
How safe is "safe enough" for you? When can we have our lives back? Or would you have us sat in our basements wearing masks on zoom calls for evermore?
