I don't think I can personally farm a Yacht into existence, so not sure that holds water. Over the last several years the "value" of several of my skills has basically gone to zero as technology advanced, so I'm not sure that I buy in the modern era at least skills are a good indicator of wealth either, nor can I likely acquire a Yacht with pure skill alone.

I guess if I am a factory owner I could produce a Yacht, but as a humble employee I'd be unlikely to experience or enjoy the produced Yacht's of the factory, and it also seems like the factory owner would sell most of their produced Yacht's for money, not "farms, factories, skills"
