To paraphrase buckminster fuller, the opposite of natural is impossible.
How we organize ourselves and socially relate today is an anomaly, historically speaking. A minor minor blip coming to an end. The spread of capitalist social relations was more imposed than organic, just ask the native americans. The question should not be what is natural, but what is healthy. Heck, genocide and slavery are “natural”.
What IS impossible is perpetual physical growth. Capitalist society can only survive by defying the laws of thermodynamics, through endlessly expanding growth, buying and using more of everything, every year and forever. Thus the cult of radical consumerism.
