Also how do I save up perishables like potatoes for a big purchase? Do I have to set up a potato payment plan? What happens when I need IT services, but my profession is teacher and the IT guy doesn’t need my services, so I have to source something he needs from someone who needs my services to get his services? What if I can’t do my job without his services? Shit gets way more complicated without a uniform non-perishable national currency, fiat or otherwise.
