Regulations are written in blood
Certificates for a job is not developed and enforced out of thin air just because we can; certificates used to regulate are created as a political construct when something needs regulating.
This insight, the need of certificates/regulations, first pops into peoples heads first when something has gone terribly wrong, or was very close to the edge of a catastrophy.
Therefore, the saying holds up terribly well:
Regulations are written in blood.
