It doesn't really matter what the AI companies 
    want, if they misjudge the market somebody will 
    just start a competitor and take it.

This kind of "free markets solve everything" magical thinking is cool when we're talking about lemonade stands, but unfortunately it just isn't reality when we're talking about markets with a really big moat such AI model training.

Even if you made the US the freest market ever, you have the small problem of your free-market hero startups needing to compete with state-sponsored models from China.

(Also, free markets depend on savvy consumers to function properly. We assume that consumers will not choose lemonade that poisons them, for instance. This works well for lemonade stands -- one assumes consumers will steer clear of the lemonade stand ringed by corpses -- but works less well when the product is more complex and people don't understand it. You know, like AI.)
