There is a third issue to licensing that dates back to ancient "law of strongmen" without even lofty claimed principles like divine right, let alone anything worth folllwing of free will; introducing a law that cannot be enforced only breeds contempt for the law. It is hard, expensive, and rare to covertly build infastructure. It isn't the case for software. Just blindly aping it would be draconian and silly. At best it could be a license for specific safety critical applications but that would be dependent upon the licensed ones actually doing a better job at being safer which is harder for the first two reasons you listed. Hell certifications are infamous for generally not being that career useful.
