Obviously, it's not feasible in urban areas where folks don't have enough land to pull off the Propane tank, generator, 4-5 PW and a ton of solar, so it's a moot point for most Californians. That being said, if you stop paying your IOU, don't they simply disconnect you? All in all, it's most likely not financially interesting to do so, but the pleasure derived from telling PGE to pound sand is close to priceless.
I know you're being sarcastic, but no, PG&E doesn't just disconnect you for non-payment. They'll keep accruing fees and a liability that they will just send to collections if you keep not-paying.
