"It's a zero sum game though"

Not quite. Supply and Demand don't quite work that way.

Arguably - if someone 'needs it' then they 'must pay' ergo zero sum ... but in reality demands for most drugs is not quite so inelastic (Ambien, opiods etc.). That said, I'm not sure what the drug in question does.

The drug in question treats a rare degenerative disease of the brain. Precisely the sort of uncompetitive market with inelastic demand that is ripe for exploitation by rent-seeking.
