I have yet to see a country where licensing equates to high quality in all the services. The examples I've used might not work in some places, but people find flaws in licensing systems all the time.

Sometimes licensing is so strict that things get done anyways ignoring license requirements because there is way more demand for some services than the supply of licensed professionals. In such cases, there are so many people violating regulation that policing becomes ineffective. It's the case with some Latin American countries.

And then you get to the problem that the license is ineffective and doesn't add to anything.

There's no perfect system to uphold quality of labor across a profession, we pick our poison and deal with it.
