There has never been a qualification required to be allowed to build software for yourself. This is unlike building a house, which most jurisdictions recognise as something that should not be undertaken by someone without the ability to demonstrate a basic understanding of the process. So, sure, once there's some bare minimum qualification that one must attain to be an "owner-builder" of software, do that. Until then, vibe-coding perfectly describes what vibe-coders do -- except for the vibes, which aren't (obviously).
