Naturopaths and chiropractors are licensed to do various things too, physicians, etc.. a license does not imply that there would otherwise exist a culture of responsibility, foundation in evidence or anything of the sort. It's an incentive structure and regulatory practice. One may even keep their license while being a monster and abusing other incentive structures that don't have a bearing on that license.

Software engineers are not typically licensed as engineers, that's all one can say without dipping into prejudice.
