> Even the most laissez faire among us would probably agree that you need to set and enforce some ground rules to prevent monopolies, externalities, information assymetries, and other market failures. Sure, of course there are ground rules. Things that are illegal are not permitted. But what are you suggesting the rule would be that would apply in this case? And by rule, we're taking about a law, right? Otherwise, it wouldn't be binding and we're right back to where eBay is within its rights to decide not sell (or list, if you prefer) these books. To be clear, I think it's fine to complain about ebay's stance here. I don't agree with it. But you can't do it in the name of free speech or liberty generally as the previous poster is attempting to do.
