What you say is true only when you define "desktop use" in a certain way, which corresponds to what an Apple PC is good for.

I define "desktop use" in another way, and for my definition any Apple PC is completely non-competitive, by having a much lower performance and a much higher price than a desktop PC using an AMD Ryzen CPU.

Apple PCs have exceptional single-thread performance, but that is irrelevant for me. I care about multi-threaded performance and especially about floating-point FP64 and big integer computational throughput, for which the Apple CPUs are weak, one could say years behind their competition, except that Apple does not make any attempt to compete in this domain.

An Apple PC may be the optimum PC for your needs and that is fine, but you should not believe that any computer user has the same needs as you.
