Ok, in the days of farms and wagons this is probably a good idea, in the days of robots replacing millions of workers and world wide distribution systems capable of abundance for all, you'll understand how quaint the answer seems.
If the people that kept walmart's shelves full continue to fill the shelves, they can take what they want and as long as they return to work tomorrow there will be plenty for all.
The banksters won't like it much, but they can go fly a kite.
As long as anything takes human effort your ideas cannot work. Taking the fruits of human labor without an agreed upon exchange is theft and/or slavery.
So yea, once we have an army of robots to do all our work down to cleaning the toilets and Star Trek style replicators - then we can live how you think.
