Maybe it's just been a long day, but I don't get your point here.
IIUC (I don't live in California, but I do live in the US), California has a thriving (5th largest in the world, IIRC, if they were separate from the US) economy based on capitalism and free (as in at least paying lip service to fairness) markets.
And therein lies my confusion. Are you saying that "This seems inevitable for a global political movement with a mission of discrediting government by kneecapping all its efforts."[0] California is not trying to discredit government and failing to do so?
Also, are there really only two options? Those being government control of everything or anarcho-capitalism[1]? Not setting up a straw man here (or at least not trying to do so), I just don't understand what you're trying to say, and it's an interesting topic I wouldn't mind discussing.
I hope you see why I'm confused by your statement. If you'd elucidate, I'd really appreciate it. Thanks!

Edit: Fixed grammatical error.
That's not a flaw in UBI, that's just an assumption that the politics would work out poorly. UBI may be impossible in the current political climate, but that doesn't mean it's a bad idea, or that it could never work.
A lot of people see UBI as a small-government low-overhead libertarianish solution to current social programs, and the universality of it is seen as making it less unfair/redistributive.
Anecdata is not data, but I don’t think this is a straw man; you just need to talk to some conservatives.
On the other hand, it’s not fiscally manageable. It costs as much as we currently pay in taxes, and we still have to pay for defense and pork on top of it. So implementing UBI would exceed our income.
This would require dramatically higher taxes which are politically unpalatable (such taxes would last no more than two years before any representatives who voted for it got voted out). The amount of money is not life changing for anyone other than the poorest. And it would cost way more than estimated due to fraud (see Medicare for an example). Plus why wouldn’t businesses grab a share of it by jacking up prices on things that poor people can now afford? From the mindset that brings you slum lords.
The market for US sovereign debt is drying up so we’re not going to be able to overspend in the profligate way we have over the last few years.
For these reasons UBI is a pipe dream.
