I don’t think this means that there should be no regulation since even basic economics teaches us that should not be the case (in the event of market failures under the standard model, regulation indeed makes sense, especially in the context of pollution, public health, etc and taxes as a way to fund these makes a ton of sense from a policy perspective).

But what the problem of occupational licensing does speak to is the need to evaluate policies for their costs and benefits in a structured, standard way and how over regulation can be a real problem even if at face value it makes sense.

Everything is a balancing act and in the context of labor markets and licensing laws, the US has clearly steered too far.
