This argument is overly general, allowing you to dismiss any expressed desires as "not real".
There is, in a sense, genuine suffering from not having a dishwasher or a bike or a basketball or a poster of the horsehead nebula even though we lived without them for millenia.
I'm not saying they aren't real desires, I'm saying that "the future can be whatever we want it to be" is hackable by advertisers and we should want some defense against that.
