Good luck getting any of that to happen. All that does is raise the barrier for proof and consequence, because they've got accreditation and "licensing bodies" with their own opaque rules and processes. Accreditation makes it seem like these people are held to some amazing standard with harsh penalties if they don't comply, but really they just add layers of abstraction and places for incompetence, malice and power-tripping to hide.

E.g. Next time a lawyer abandons your civil case and ghosts you after being clearly negligent and down-right bad in their representation. Good luck holding them accountable with any body without consequences.
