Once again: if this thread or the expressed ideas are worthless or senseless to you doesn't means they are worthless or senseless to everybody.
Nobody is a golden standard.
Surely the only 'golden standard' is logic. Only then can it be 'sense' as opposed to 'senseless'.
I have no problem with you (or anyone) holding a definition of art, but when a scientific concept is introduced to support their position and that concept fails at the most basic level of enquiry, challenging it will enable 'everybody' to make their own minds up as to its validity. Is this pedantic? Probably. Is it necessary? IMO, yes. Otherwise positions become inarguable, supported by irrelevancies and non-sequiturs.
I will leave it at that. Have a good day.
