Earlier quoted context omitted.
Everything is a market. Any time people get together, for any purpose, trading occurs. The truth of that assertion hinges on us not remembering the billion other counter-examples. It might comfort free-market capitalists like ourselves to paint humanity with that thick brush, but truth tells differently: people don't always gather with the intention to buy/sell, in fact, sometimes, commercial intent is detrimental to…
Just that trading occurs anywhere people get together doesn't mean everything is a market. I'd have liked to +10 you. It's so hip these days to see everything in the context of economics, as a market. In my opinion that's actually hurting our understanding of human behaviour, by trivializing every interaction.
I think many times we get the simple fact that humans are traders mixed up with all this political and economic theory nonsense. To acknowledge that people are always trading is an important observation in itself, and doesn't imply any other conclusions. Draw your own.
If anything, it looks like the study of economics is doing exactly what you say: it's showing that these trades many times are irrational, are not for money, and are driven by as many complex forces as exist in the human psyche.
So you can start with "it's all a market" and end up with the complexities of human existence, or you can start with "It's not all economics" and end up with the complexities of human existence. Same difference. Either way, the problem is taking huge generalizations and beating them with a rhetorical hammer until they fit some personal worldview, not the observation of the phenomenon itself.
