Right, we're too busy building choo choo trains to nowhere. But even if this stupid state try to build more dams, the econazis would fight endlessly to make it unfeasible. They don't want sound water policy. They want depopulation.
Sounds like the possibility of a win-win situation there. Start building reservoirs. When the greenies self-identify by fighting it, depopulate them. Rinse and repeat. Eventually the reservoirs are built and the greenies ae depopulated. Everybody wins! Everybody got what they wanted!
