if your sole goal in life is the relentless pursuit of as much cash as you can possibly grab a hold of on your short time on this planet, then you are right.

If you have a soul and aren't an awful creature that sees the world as a series of zero sum interactions, other concerns play into this. Things like you actually enjoy the work or you feel proud of making the piece or you care that every last detail is as perfect as you are able to make it.

Now I won't say that it's never right to use AI (goodness knows I do). But its totally wrong to suggest there is "no point" in ever doing things a different way from the cheapest possible technology

This is myopic “Silicon Valley” rhetoric and lacks understanding of art or why it’s appreciated.

We have video cameras and movies, yet stage actors on Broadway are celebrated like movie stars. People still read books. We have cameras and photoshop, yet a huge market still exists for oil on canvas. We have synthesizers, drum kits, and all the tools we need to make music on a computer, yet live concerts with guitars and drums sell millions of tickets annually. We have the technology to deliver payloads on another continent with millimeter precision, yet every few years, the whole world gathers to watch people who have trained a lifetime to run, jump, and throw stones.

“The old way is dead” doesn’t hold up in the arts like it does in the sciences. Technology moves on, but humans are the same. You can inspire and awe us today using the same tools and methods that were used hundreds or thousands of years ago.

Please understand that when you think of artists as "creative content authors" you are already off-base so any argument you make based on that is going to be incredibly wrong.
