You can also buy from companies that hire licensed software engineers if you want to? The main thing that would stop people patronising licensed individuals is if there was no obvious skill gap between a licensed and unlicensed practitioner that justifies the price gap.

People don't need a government body to tell them to check for credentials. If people care they can ask (I had to give a copy of my degree certificate thingo to my employer a job or two ago, they cared that I was qualified). The whole and only point of mandating licensing is to raise prices for consumers.

EDIT

Just while I'm thinking about it, the law is expected to be easy enough for everyone to follow while simultaneously there is is an absurd legal fiction that only a licensed professional can talk sensibly about the law. It is internally inconsistent that lawyers would require a license.
