>Now it's true that the cruise ship passengers skewed significantly older, but on the other hand, they were all ambulatory and healthy enough to be taking a cruise.

While yes this is true technically, I'm not sure the bar for "healthy enough" is as high as you're making out it is. In my experience (apologies for the anecdote), significantly obese people are quite capable of going on a cruise almost always.

I'm talking about people in nursing homes, people in hospitals, people on immunosuppressants, for example, after a transplant (who wouldn't go on a cruise because of norovirus etc), people with other immune diseases, etc. There are a lot of these people out there, and these people would be very hard hit if we just let COVID run through the population.
