Assuming a libertarian online marketplace, governed by the hippocratic oath (http://www.wh.com/cmem/codes/hippocraticoath.htm), what is the best structure for handling liability?
For example, someone orders a bag of marbles and some LSD. They take the LSD, then put the marbles into their mouths, fall asleep, suffocate and die. Is the website that provided the marbles and LSD responsible for the death?
Do members of the online free market release the vendors of all liability, before membership in the "sacred marketplace"?
Does the online marketplace provide CBT, automated diagnostics, and drug interaction warnings with each wholesale shipment of pharmaceuticals? Do they maintain case records of customers? Hmmm?
