If you watch the OP, you'll see that the construction of this aqueduct caused billions of dollars worth of environmental devastation. Rail all you want against regulations, but when an argument boils down to "I wish we didn't have to internalize all these costs and could just push them off on someone else", I'm not especially sympathetic.
LA has paid billions to remediate, but the actual cost is incalculable. Not sure who is "railing against regulations" but there are obviously downsides to heavy environmental regulations. Debatable if CA is striking the right balance.
