What gives the original seller an inviolate right to the potential purchasers? It's an OPEN MARKET. Anyone who wants to can speak up to RAISE the price; why is it so terribly immoral for someone else to speak up to LOWER the price? That's what the whole free market thing is about. Competition. You seem to think it's somehow morally wrong--leading you straight to hell!--to sell an item in a public channel while someone else is selling the same item for more.
You failed to explain what distinguishes it from a buyer outbidding another. Despite whatever that 2nd buyer's intentions may be, he is still doing a great dis-service to the original buyer, or doesn't he matter?
