Of course the point of a license is to help those who can get licensed at the expense of those who cannot. The ethical systems of licensing have a point, where society wants to favor those who can get a license. Driver's licenses are a good example of this - we as a society want to artificially restrict the supply of drivers to those who can pass examinations for vision, knowing the rules of the road, and ability to follow certain professional rules (eg, not driving drunk). Or electricians, where the cabal of people who know electrical code has a distinct advantage for society (that is, not burning down their buildings via faulty wiring).
