Over taxation is one of the primary stated reasons some rural Californians are proposing to split the state.[1] So perhaps a solution is to allow farmers to govern themselves and tax land owners appropriately, and big city dwellers to govern themselves, taxing land owners appropriately.
(Note that I don't live in CA so I am neither for nor against. Simply stating facts.)
