I think the argument perhaps needs to be separated out into two strands.
That is a lot of arguing.
If your essential argument is that - measurements don’t reveal how a component sounds and that the reveal even less how a component will sound in a given system - then by and large, I agree with you

The exceptions to the above are that certain measurements of amplifiers do correlate pretty well with subjective sound quality.
I agree that they sell power numbers on receivers with either two channels driven or all channels driven, this is inconsistent. As long as they state which one I wouldn’t say its bogus.
I still feel that it’s a leap of logic from there to concluding that measurements are not useful.
I am tired of bogus measurements, the publisher of the measurements can be matter of fact, like stereophile or simply foaming at the mouth with anger trying to shame not just the company, but their customers. It isn’t just ASR, audioholics does this too along with goldensound. You can find a product YOU like that didn't measure best in class. The opposite is also true. You have no idea how a group of products will sound when assembled, in various rooms, based on anything, especially bogus measurements.
