Governments set the rules of markets... How could governments adjust the rules so that developing cures makes business sense again?
The idea of selling of goods predates any government. In their simplest form, how a market operates is determined by the agreement two people, a seller and a buyer for an exchange
When restrictions are applied, how the market operates is still determined by how people interact within those rules or by how they attempt to circumvent them to make their exchange.
This is not a unique case.
