>Instead we have these laws that encourage stuff like a single dude living alone buying 3 cases of water at the gas station and the family of 6 who arrives an hour later can't get a single bottle. Or the dual with dual tanks in his pickup truck filling both up and the folks who come by in their Civic needing 1.5gal to evacuate can't.

What if the single dude has 1000$ and the family has 10$? The single dude can obviously just buy all the water and the family still gets none.
