I know how to do something people will pay me money for. I can wander from urban center to urban center around the world (today literally or via the internet), and people will still pay me money to use my knowledge to build stuff, much like medieval stone masons (who didn’t just cut and lay stones to build beautiful cathedrals, but utilitarian structures too). Meets my definition of a craft.
