You seem to have missed this statement in the post you are replying to.
"In fact, as another freeper has shown, the CA Secretary of State is compelled to put the major party candidates on the ballot, with no discretion allowed. So that's not the law either."
Incorrect. She has the responsibility for all statewide elections and candidates. The code is very specifis about that. You are confusing the Nov presidential election with the primary elections in each state.
