Earlier quoted context omitted.
There are many people who will die from many common diseases that are communicable, including the standard flu. This argument doesn't hold up under scrutiny. At risk people (the vast, vast minority) need to self quarantine instead of having the unrealistic expectation that the everyone should instead of them.
I see you are planning to spend your golden years sheltering entirely indoors with others of the vast vast minority? ie. the over 60-70's.
60s is a different thing, but at 70 there are very real questions about whether a quarantine is even worth it. Do you risk losing half your remaining lifespan in a quarantine, attempting to avoid a 30% chance of death? The calculus is grim, but that doesn't mean it should be ignored.
