Why would you want a license? The whole allure of software development is in its accessibility, that it's easy to get started with nothing more than a laptop and an Internet connection. Putting up artificial barriers to entry is anathema to that. What you'll end up with, in practice, is one of two outcomes:
1. A race to the bottom where licenses become easier and easier to get, until it becomes no more a demonstration of competence than drivers' licenses are to one's driving skills.
2. Protectionist policies make licenses mandated and difficult to obtain, then the talent pool and innovation moves to places that don't require that license.
