Capitalism (especially the free market kind) has been most successful when it has been used as a pragmatic tool, instead of a dogmatic philosophy.

So basically, my answer to "Why Capitalism" is that "it works".

Capitalism cannot (rather, should not) provide you with a set of ideals or principles. Capitalism is a tool to achieve those set of ideals or principles, and should be used where appropriate in order to achieve those ideals and principles.

The ideals and principles have to come from elsewhere.

Elon Musk and Bezos believe in the principle of a backup planet, so they leverage capitalism to reach Mars. Bill Gates believes in book recommendations and charity, so he leverages it for that purpose. Someone who is closer to an employee believes in a building a good life for themselves and their family, and they use capitalism for that.

The article is like asking "What's the point of a hammer when once you've used it to hang a portrait you put it away?"
