One argument that got thrown around a lot was that people in the hospital with COVID are taking medical resources away from others. You could make the same argument for people who choose to drink, smoke, remain obese, sedentary, have untreated diabetes or other chronic conditions that will eventually put them in the hospital needing a lot of very expensive care.

Those conditions don't overwhelm hospital capacity because they don't produce exponential growth of illness, so I don't think you could make the same argument.
