But there's not even an attempt to compare risk quantitatively. Cabin depressurization events are extremely rare, and deaths from people who don't manage to put on the mask (which will exist on every plane) are rarer still. This is a known, negligible risk, while covid is an real and still difficult to bound risk. Passengers should be allowed to make that decision themselves. (And regarding blocking the way for others: as long as it's easier to get by them than to get by some of the very large people who are allowed to fly, that should be OK too.)
