Yes, I know it is a necessity in this international and interconnected culture of ours. I wouldn't try to barter a basket of aforementioned fruits at the tobacco store, or offer my services to paint the clerk's walls in return of some smoke. Oftentimes it would be hard to find a tobacco store where the flat of the clerk or owner needs painting, and the fruit option would be nonexistent in the winter. And I wouldn't even know whose flat to paint and how often if I wanted a continuous internet service. But it won't make this system of bartering large quantities of IOU notes any less stupid upon closer scrutiny, because of the mass delusion aspect.
What I wanted to mention in my previous post, but totally forgot about it by the end, is how that big family system and similar close community ones were/are able to circumvent the system and give you that sense of pride in individuality (however strange that sounds) more than any number of Nike ads ever will. By people, be it relatives or neighbours, helping each other out, you are getting rid of the state and other players as middlemen, making everything a more personal thing. You have all the wheat in the world, but you want to eat meat with your bread? Pigfarmer Joe will gladly barter with you. You need new warm clothes? Auntie Marjorie on the other side of the village will gladly knit some for you and your family for that fruit basket. You are building a house? There's a dozen brothers and cousins living nearby who will gladly help you out. In return, you will gladly help them out when they are building something. Everything is personal in such places, and you don't have to deal with the faceless, dehumanising consumersim while trying to solve those problems. No shady, low quality import meat, no chinese slave labour clothing, no drunk-ass moronic prole construction workers. And much less VAT and other taxes paid, so the guv'mint, be it capitalist or communist, doesn't really like such communities. Also because they are prone to listening to official propaganda much less, as they tend to get their ideologies from their elders. Hence the methodical destruction of the big family system during the last century or so.
