Tell me before you abandon IP-law so that I can withdraw all money from medical research. Copying a drug is dead simple but finding a drug that is actually effective takes years of research by highly skilled professionals, not to mention expensive testing and clinical trials.
Now there is a good one. So why is a drug 'recipe' copyright but a food recipe not copyright?
Both the fashion industry and the food industry are areas of very little copy-right and both seem to flourish without those artificial controls.
