To some extent yes, but that is different from the claim, which is about "all money." But also, you're neglecting things like cheaper parts tending to be worse for the environment. Comparatively expensive wood, for instance, would likely cause fewer problems than cheaper plastics. Plus, that's true by virtue of the cheaper parts breaking sooner and needing to be replaced. It's certainly not a universal that luxury goods are eco-friendly, but it is true that eco-friendliness is a factor that requires a premium to be paid for it.
