The problem, as you have rightly pointed out, is money. I'm going to assume from what you said that you are not a multi-billion dollar company. If you are, please disregard the rest of this comment..

When WotC and others like them use AI assets instead of hiring artists, it means that they have to give less money to working-class people to create their product, but they will still charge the same for it. This leads to even more money being siphoned from you and me into the pockets of giant corporations and their disgustingly rich owners.

(This is in part what the actors / writers were on strike about recently - not wanting AI generated content taking them out of a job and not giving credit)

As it stands in America (WotC's home) right now, people need money to be alive. It's a ridiculous way to run the world that you need to buy food and shelter, but that's not changing any time soon. This is why AI and other automation is such a problem.

When you use AI to help build your game, it is a regular person (you) who is benefitting, not a giant corporation. And as you said, without AI then your game is less likely to progress and no-one gets to experience the work and passion you put in.

Bonus thoughts: I'm all for taking away people's jobs and replacing them with a universal basic income, or doing away with money all together. Why should people need to spend 40+ hours working when a machine could do it better? Let people be free to pursue their passions and goals without needed to worry about where their next meal is from. All of these wonderful technologies that humans have created should be freeing us up. What we need is for our political and societal structure to catch up with our technology!
