What of ratings or vetting forces someone to work more? If you sell once at a fleamarket and acquire a word-of-mouth reputation for your actions, are you forced/expected to come again? It's irrelevant why a government would act, political or fiscal reasons are always part of it, and protectionism. This doesn't have bearing on whether it is making sense or being illogical.
