The key to lawyers and doctors losing their licenses to practice is that they have professional bodies that will police/enforce the rules. However, they also have a monopoly to provide those services.
I suspect corporations don't want limit software engineers to those with licenses only as there would be less of them available and costs of said licensed software engineers would increase.

It comes down to money, which includes liability. I suspect licensing won't ever happen in software unless law suits increase and licensing becomes a deterrent, at which point licensed developers will cost less after factoring for risk assessments. There are all kinds of unintended benefits for everybody that come from limiting negligence, which pays for itself. As a counter argument who benefits most from allowing the hiring and practicing of negligent developers?
