I agree with your overall point, RxKing, but I wouldn't really agree with your numbers. I do think that your interpretation of supply & demand is too limited in scope though. If it's not obvious what the choices are, then it doesn't matter what the supply is -- it may as well not be there.What I'm saying is that for every person who does not bother looking at every page of the listings, some of the actual, real supply does not matter because that given person did not even know it was there -- it makes no difference for their choice whatsoever, the guy's listing may as well not even exist for that purchase. Is it meaningless altogether? No, of course not, some people will see it and maybe it'll get pushed toward the front of the search results & fewer people will miss it. But the point is that for every single person who does not check every single page every single time, the supply & demand thing isn't even reflecting the reality of the supply. That's bad for the market (by western standards anyway).That's the real reason I think there's actually something to the point that it hinders competition and all that stuff that make the things here on SR generally cleaner & more reliable. Nobody's asking for anything except the search function to accurately reflect the supply available.
