The Kern County vote only affects unincorporated areas of the county. California City's plan to offer MJ permits is not affected by what the county or city of Bakersfield do
Your argument hinged on the claim that if Kern County banned MJ, mCig wouldn't be able to build there. We don't have to prove that mCig is building in California City. For your argument to hold, you have to prove that it purchased land somewhere that MJ is banned. At this point there's no evidence that it did.
