Here's the problem. The citizens of California who think the way you do believe that the second amendment protects their RKBA. One day they will wake up without their guns and wonder what happened. If they had listened to you, it's now too late.
The time is now, there is no later, for the citizens of California to write an RKBA into their state constitution.
Pretty worthless philosphy isn't it? Yet you're perfectly comfortable applying it liberally (pun intended) to the Commerce Clause.
