It makes perfect sense. That is not required for my argument to make sense, 30% of healthcare costs is staggering, and absolutely could result in higher costs or worse outcomes for others.
And a spike from one particular cause does not necessarily lead to a shortage. If a few extra patients start getting covid and then there is a bed shortage, then fewer overweight people in there might also have prevented the shortage.
Look, it's for the greater good. No use arguing against it unless you hate grandma and Science™.
