> Physical attractiveness is a signal of reproductive fitness when it’s genetic, and not otherwise.

Nay, artificial physical attractiveness is also a signal of reproductive fitness. It isn't a given. It's the subject's genes that made a brain that was able to design (and to arrange to pay for!) the improved attractiveness.

It's not qualitatively different from brushing hair.

Yes, technically, having spare resources to devote to your own appearance is considered a positive signal, but it is an unreliable one, and often one not as valued by the people making the judgement. If there are many ways to signal wealth, a signal that has some intrinsic downside will lose its value if lots of people are sending the other wealth-signals.
