Interesting, I s'pose it was a good idea in theory, but if ever implemented all bets were off. In a real emergency with people thirsty, starving and cold, best intent and private property rights would have gone out the window. Private property held in a communal stockpile is something of a non sequitur . . .
OTOH a real community/publicly owned survival stash implies public spending of city/state tax revenue. Can Oregon communities do referendums?
