If we didn't have to worry about money, then fewer of us would have to... worry about money when making art.
> We now have enough people with skills, experience, tools, and free time necessary to produce a quality indie game and a desire to make one, that the market price is far below the cost of production, and rapidly approaching zero.
Where "free time" is that not used up by work that pays for food etc.
Which does mean that people for whom art is a hobby are destroying the market the people for whom art is all they want to do, except for truly great artists where the quality of the art is so exemplary that hobby artists just can't compete.
But I'm not sure why it's a bad thing in and of itself - nobody has a fundamental right to earn a living by performing some specific activity and no other. The job market defines what activities translate to paid jobs, and which ones can only be hobbies, and that is going to change over time. At the point of a true post-scarcity, everything becomes a hobby, but it doesn't matter because you no longer need a job.
post-scarcity can sound nice, but in practice it currently means post-scarcity for the few, while most people live with incredible scarcity. We might have enough for everyone on the planet, but we sure don't share it equally. And that's not going to change automatically.
When and where the goal would actually be achieved is hard to speculate; I hope to see it in my lifetime, but only out of sheer optimism.
