Insisting on getting paid for work is very different from insisting on owning a scarce resource in order to force others to pay you for it as much as you can squeeze from them. They are moral opposites, one is about not being exploited too much as an individual and other is about exploiting everyone.

My comparison is not entirely fair, I'll grant you. But stoking resentment between the countries who have produced vaccines in record time and less fortunate countries that need them is also not helpful.
