The whole reason the cost is high is because there is scarcity.
You’re not “getting the rich to pay” - you’re preventing the poor from accessing the drug, placing vulnerable less wealthy peoples life’s in danger because you prioritised doses for people who can pay (who would _get it anyway_ if they had a risk factor).
You’re literally trading a risk on one persons life for somebody elses money.
Not to mention the moral issue of “how many doses are set aside?”, because why not sell all of them for $25k if that’s the price you can get?
