Given the socialists cooking up this scheme, you can expect it to be progressive, i.e. premiums based on your income and services provided on a means tested basis. A bonanza for illegals and a major screw job to people making a decent income.
Just more government control over your private life. As I have no interest in living in California, I say let em have it. Then watch the state disintegrate. We do need a test state, ya know.
