Well, there appears to be some demand for a straw hats on the market (you tenne )
And IF someone actually had a +3 straw hat, wouldn't he have a monopoly position?
I know a couple of people who (Allegedly) have straw hats (names are disclosed since I WANT to be the only demand) and that means that because I am demanding, the supply is greater than the demand causing a "competition" meaning that there is no monopoly.
Also, due to the fact that basically everyone has the chance to get everything, it creates a sort of "perfect market situation" which damned near impossible in the real world because there are too many different things that can give an advantage. Unforunately me, just wearing a straw hat really doesn't give it any special properties other than the fact that "it attracts aggressive people" that attempt to kill me, but that's because of my whole outfit, not just because of my hat.
Therefore in my eyes, I have the only demand and the supply is greater for something that is worth a lot less than something more useful, pushing the price down, and if that's not the case, then I will push the price down anyway.
