It sounds like there would be a huge competitive advantage in starting your own company and doing just that. You can pay much less, get much better work, and rake in the profits as you shut down your idiot competitors one by one.
That's probably overstating the case a bit. If you're hiring remote workers from other parts of the USA, I'd say you can pay somewhat less, get roughly equivalent work, and reap the profits so long as you have the skills to manage a distributed team.
Because many of the workers who are "good" come to the Bay Area for the money, the lifestyle, the location, and the job selection. If you could, why would you not want to live in an excellent climate by many of the US tech companies and make 3-8+x what you'd get elsewhere? You also typically get to work on "cooler" stuff since the companies out here can afford to make bigger and riskier bets. There aren't too many AI/ML positions around the rest of the country, but it's hot right now here.

Because California, number one, and because everything costs 3-10X what it does elsewhere. I could easily double my salary if I moved to SV, but I'd have to live in a van in the parking lot like a hobo, instead of being able to afford a decent house and have a goodly amount of disposable income.
