The good news is that discovering more efficient ways to do the same thing other people were already doing is an excellent route to entrepreneurial success.

The only thing I’d consider truly anti-capitalist is a law code that prevents them making such decisions (by taxing and regulating them, or by subsidizing the things they’re “supposed” to want according to experts or a democratic majority and its representatives).

A best-selling book counseling simplicity and asceticism would certainly seem consistent with capitalism as properly defined — and so would a poorly-selling one.

And this is an important point, one perhaps oft misunderstood, so I thought it worth replying in a fairly serious fashion. Put another way: your hippie commune only threatens my capitalist system if you seize land for it via eminent domain or start trying to “legislate” the behavior of neighbors. Good neighbors don’t legislate, and decent human beings don’t govern each other. What they buy and sell (or don’t) is their own business.
