I think it's time to reconsider a lot of state licensing regimes. But the fact that they're licensing regimes isn't what makes them bad. Licensing regimes are a perfectly reasonable way for the state to control behavior that involves negative externalities. I think almost everyone agrees that governments shouldn't allow factories to be created in residential areas, or allow drivers to drive without liability insurance.
And we don't necessarily have to take every single view seriously. The vast majority of people don't want a massive polluting factory built next to their single-family home. The fact that a few people disagree doesn't mean that every project get bogged down in a discussion of the legitimacy of zoning as a concept.
