Sure you can, but I wouldn't make that argument about the NFL. They exist to enrich 30 owners and Roger Goodell. They don't even live up to their own mission statement - most fans deride it as the No Fun League.
Fast fashion and fashion industry in general is useless to society. But rich jobless people need a place to hangout so they create an activity to justify.
fashion allows people to optimize their appearance so as to get more positive attention from others. Or, put more crudely, it helps people look good so they can get laid.
Not sure that it's net positive for society as a whole, but individual humans certainly benefit from the fashion industry. Ask anyone who has ever received a compliment on their outfit.
This is true for rich people as well as not so rich people - having spent some time working as a salesman at H&M, I can tell you that lower income members of society (like, for example, H&M employees making minimum wage) are very happy to spend a fair percentage of their income on clothing.
It goes even deeper than getting laid if you study Costume History and its psychological importance.
It is a powerful medium of self-expression and social identity yes, deeply rooted in human history where costumes and attire have always signified cultural, social, and economic status.
Drawing from tribal psychology, it fulfills an innate human desire for belonging and individuality, enabling people to communicate their affiliation, status, and personal values through their choice of clothing.
It has always been and will always be part of humanity, even if its industrialization in Capitalistic societies like ours have hidden this fact.
Clothing is important in that sense, but fashion as a changing thing and especially fast fashion isn't. I suppose it can be a nice hobby for some, but for society as a whole it's at best a wasteful zero-sum pursuit.
There was a tweet by Elon which said that we are optimizing for short term pleasure. OnlyFans exists just for this. Pleasure industry creates jobs as well but do we need so much of it?
