I think you just obviated about 200 years of economics debate.
I don't mean to sound trite, but that's basically a resolution of the whole debate between the subjectivist/marginalists and the "labor theory of value"/"cost the limit of price" camp.
I'm not an expert in the history of economics, but I don't see how anything I said is controversial or obviates any debates. I find it hard to believe that any economists think that consumers do not consider these things when deciding what prices they believe are fair.
I don't claim you were the first to come up with that resolution, but it's an insight without which the two camps were effectively talking past each other, unable to identify where the real disagreement was.
