The problem is that there's a little more nuance than just "utility". As an example, take clothing. I don't think that anyone would argue that a single t-shirt didn't have utility. After all, I can wear it. However, I have several t-shirts from conferences or conventions that I don't ever wear. So while they have utility in theory, I'm not utilizing them in practice.

Yeah, I thought of that but I think you could take all those Ts and then the first one and second one would have utility (one while the other is in the wash) then each subsequent one would have less marginal utility, till some cut-off.
