I'm not sure if you're saying that quality has physical measures. A quality program eventually gets down to physical measures, such as how flat the sole of a plane is.
But the larger question is whether the customer puts any value on what you're physically measuring. Let's say that one company can hold their plane soles to within 0.000000000001 inch of flat, while another can hold their plane sole to within 0.000001 inch of flat. Is the first "higher quality"?
The answer is in whether the customer cares about it.
Engineers always want to say that quality is conformance to specifications - but the really important question is whether the specifications help you sell your product - whether the customer cares about those specifications.
So, sure, you can define quality to be anything you want it to be. But there's legions of people who shook their heads during bankruptcy proceedings and said, "But I always built a quality product." Yep, a quality product by their definition, but not by the customer's.
