Some supermarkets here have put limits on how many you can buy of essential goods so I don't think its a very radical idea. I don't think we need a full rationing system with a rationing book ect. like in WW2, but there are controls we can put in place to limit people from hoarding more than they need of essential items.
What would be your idea on how to move forward on this?
A limit on how much you can buy of each essential item in a shop. It can be flexible so restrictions could be added and removed on items depending on the situation.
and these limits work because theyre imposed by the shops themselves- not by governent command who would no doubt cock it up.
