Whew! You certainly said a mouthful.You may form a hypothesis with such subjective data but what you said for the most part is not true, and is certainly misleading.
This isn't debatable unless you think you can get everyone to agree to change the scientific method, which is here for your reference:
Scientific method - Wikipedia
en.wikipedia.org
There is therefore a clear delineation between subjective and objective, unless you think you can get everyone to agree to change the definitions of the words. I'll leave it up to you to google the definitions.
The "measurements battle" will end when science defines the precise relationship between measured phenomenon and subjective experience. If you think this will never happen I disagree, I think it's just a matter of time. Currently it's stalled out because there is little financial incentive to do the work except for audio businesses, and they will only share information if they think it'll help with marketing.
I understand why you said what you did but IMO it's not helpful because it's not true.
Fortunately not all scientific research is funded with an eye toward making a profitable prodict.
I think a huge impediment is the claim that we know it all or what we don't is not worth knowing.
