Most people will not be happy living on food stamps and haven't fulfilled their demands (housing, clothes, healthcare, education, transport etc). This model won't sustain even for single decade and finally end up in a bloody civil war!
by payment in food stamps/ post scaricty money, I was talking about "fundamental human rights money" aka food, water, shelter, transportation, education, internet, literally everything we take for granted today. Since these in our society will most likely be provided to us at no cost due to perfect economics (M2M transactions) and robotic manufacturing, none of these will be of significant cost to create.
What this does is something that another form of work would do, it creates compassion and empathy in people helping those that couldn't help themselves, it might be a little idealist to assume it would actually work this way but its better than class warfare / running in hamster wheels for money.
