You wouldn't believe how rare it is for me to meet someone who agrees with this. I'm in leadership at a web3 company and I need to reiterate this point over and over again. NFTs don't have intrinsic value OR arbitrary value. ERC20s don't have intrinsic value OR arbitrary value. If it doesn't tie back into user psychology, it's not worth anything.
Interesting historical note is that one of Freud's original metaphors for understanding the nature of desire was the unconscious "investor" or "capitalist" who outlays affective charge to the conscious "entrepreneur", who relates to objects. This is known in the literature as Freud's "economic metaphor", which I've found immensely helpful in my own understanding.
