I had the exact same thoughts; I grew up in California, went to school here, and now work here. You can claw the Pacific Ocean from my dead, penniless hands. The vast majority of my network seems to feel similarly, even those that did not grow up here. There is a constant saying that’s get thrown around in my company at least: “I will retire in San Diego”. To us:

Seattle is too dreary, slightly too white. Austin is way too white and you are still in Texas (state politics don’t sound like a feels good) New York is too crowded, but in my network this is the obvious next choice: we are told stories in sf that the homelessness is better, techies are in demand and treated well, dating is better for men. LA is where a lot of my network wants to be but companies aren’t growth oriented, we would be stuck in traffic more of our lives, which is why a lot of us left jobs in the valley. My network is primarily techies 24-32 years old, so I’d imagine “growth oriented” may mean less to us in 5-10 years.

Of course this all anecdotal but still relevant and indicative that a certain portion of people who live in California (even transplants) will not just live any where.
