I am saying that the purpose of good UX is to lead to some sort of conversion whatever that might be. Whether that's buying, using, submitting etc doesn't matter but you can't measure something you don't put measurable metrics around.

I discuss UX all day long and have all sorts of discussion around various approaches, have principles and strong opinions on various UX related issues, but I would never claim it's a framework that can be used to judge the UX in itself unless I am willing to put it to the test of something externally and quantifiable.
