Wow, there're a lot to parse here, and it looks like you're coming at this from an "I've already decided" and "axe to grind" angle.
> - Lockdowns did little to prevent the spread of COVID...
> - Cloth masks were pointless security theatre
- and most rational people (and countries) immediately switched to N95 masks as soon as supply chains could support the demand. That said, I'd bet that even less-proven masks would have some lesser but still positive impact.
> - The vast majority of people except the very elderly and obese were in very little danger
...except there are plenty of examples of fit, young people having life-altering acute and/or longer-term symptoms. On a population-level, you're right that the numbers are small(er), but I'd argue that each individual case to the contrary is a disaster for the indiviudal involved.
As Stalin said: “The death of one man is a tragedy. The death of a million is a statistic.”
You appear to be looking at the statistics; I was happy to accept changes to my lifestyle to diminish risk of harm to individuals.
> - The vaccines never prevented transmission
That's a straw-man argument - that's not the primary purpose of a vaccine.
> - The vaccines only offered very limited protection for a brief period
Nah. Vaccines offered significant protection against severe disease for a period of months (which itself is a factor of how the human body function). With widespread vaccination, the world was able to 'get on top of' the pandemic, and its effects of healthcare over-utilisation.
> - The rate of side effects (including serious side effects up to and including death) is a lot higher than anyone wants to admit.
> - To most segments of the population, the danger of death by vaccine side effects is greater than the danger of death by COVID-19
