For anyone who has matured past concern only for themselves, serving their peers by providing value in the marketplace voluntarily contributing value for value, with free market pricing (for the wisest among us priced in sats) is a natural evolution of healthy and mature personalities. Only adolescents think ONLY of themselves without any desire to serve their community of peers. Contributing properly compensated value to society at large is how we capture more sats to help solve the problem of 'coincidence of wants' that brings us all the benefits of specialization.
No man, nor family, is an island. As Bill Mollison put it "True security comes only when you look out your window and see your food growing and your neighbors working." Once that need has been met, serving your community by delivering goods and services that empower them to do achieve the same is a natural consequence for all but self absorbed narcissists.
