1% Yes, and 99% No.
Over 99% of uses would not have resulted in hiring someone to do the work had these models not existed as you yourself acknowledge.
Those numbers are also a bit too aggressive - it's easy to miss what kind of gig work exist out there. PowerPoint as a service is a thing on Fiverr for example. A horrible, horrible thing, but a thing none the less.
^1: not at all what art costs, but someone trying to get started might do quick sketches at those prices
Or 3. Something I made and I actually use, but I would never have paid a kid $5 to do.
Yes, I know of Fiverr and similar sites. Even planned on using it once. Even know someone in another country who made side money from it. And yes, it does suck for them. But none of that changes the fact that well over 99% of uses are not depriving them of any money.
You may look at the output and say "Crap!", but the reality is the person using it found value in it.
(To be honest, I used to think "Crap!" to stock photos long before LLMs came on to the scene, so I have little sympathy with stock photo photographers going out of business - those photos exist primarily to attract readers and do not provide any value to the content - they're just like ads in that regard).
Not pointing fingers or saying that you must pay kids to draw things for you, but it most definitely does take work away by replacing an entire class of commissions. Not sure what to do with that fact.
(I'd put things that would never, ever be worth a $5 commission into the throwaway noise category, even if you do use the outcome.)
