From the viewpoint of most countries in Europe it would be considered "very liberal".
(EDIT: Also the source you mention is clearly politically biased. https://en.wikipedia.org/wiki/The_Heritage_Foundation )
However, academic studies from two accredited institutions that don't have a particular ax to grind are probably equally credible.
Of course Heritage is biased. But their Index has a well defined methodology and provides the data that informs the final score for each country; it can stand on its own, and should be criticized as such.
Occupational licensing has some overlap, but regulations are often very good for very big businesses since they impede competition from small challengers. Anyway, I'm mostly sympathetic to your points, but it's important to distinguish between being 'business friendly' and being 'friendly to status quo corporations'.
And we're a good bit worse than 11th there.
Licensed hairdresser? Fuckoff. Licensed doctor? Sounds reasonable. Lawyer? yeah. Engineer? Probably. etc...
Insurance salesperson? maybe.
Really depends on what the license is intended to protect. if it's just a silly barrier to entry that's one thing. If it is to ensure that a person has a minimal level of competence so as to prevent real harm to their customers that's a different thing. A lot will claim to meet the latter standard, I'm skeptical how many do. Insurance sales licensing I would guess to be mostly the former.
That being said, you spend 2 weeks getting licenses sorted out when someone starts and you avoid this whole mess.
