Land is cheap in rural areas, so parking would not be very pricey there.
Lastly, the edit to your post is nothing more than the implied claim "is == ought". You never actually give a reason why people living in rural areas deserve to be subsidized at the expense of city people. We may have historically forced city folk to subsidize rural folk, but that is not a reason to continue doing so.
