Thanks for listing what you consider the stupid environmental policies. Before you did that, I was thinking you must be referring to the idea that farmers should grow high water crops like rice and almonds in a state naturally prone to droughts.
OP, homeschooling in CA is easy and without oversight if you register as a private school every October. It's a simple online form. If you choose to homeschool under a charter, there is more oversight in the form of annual testing and monthly check-ins with the charter, but you are given money for approved (non-religious) materials and activities.
The Bay area has a high concentration of Buddhists but we also have a high concentration of Asians (~24% of the population) so I can't speak to how many temples are mostly set up for people speaking a particular language. This link may be of assistance in looking at different states (scroll down).
The Bay area is very expensive so if you get an offer to move here and you think the salary looks really good, be sure to check it against a cost of living calculator. The cost of housing can be incredible unless you live inland a bit. Rents are particularly high right now, even higher than the cost of owning.
Homeschooling acceptance is good. While there aren't tons of coops like in some areas, people are generally positive and there are social and field trip groups.
