nah, still sounds protectionist to me.

there are broad based wage gains and better prices for consumers when anyone is allowed to be a driver

Always with the prices.

There is more to a functioning society than the cost of goods and services.

Regulating market is reasonable thing to do.

Sensible limiting of service providers ensures that prices are not driven through the floor. Like setting minimum wage.

Also regulation could allow capping of the prices.

And there is nothing that says that such licenses must be transferable or sellable.
