Yes, we always have to think about perverse incentives and the resulting unintended consequences. But some of these problems can be remedied with more government involvement. E.g., instead of allowing BigPharma to reap windfall profits (via artificial IP monopolies) to finance R&D (which they spend less on than they do on advertising), why not treat drug development as a public good and finance it accordingly? (We might see less investment in Viagra and more in anti-malaria drugs.)
