Accidental regulatory capture seems to be more common than nefarious intentional corruption when it comes to policy reinforcing monopolies. History is littered with examples of well-intentioned policies backfiring.
The rat pelt bounty in French Vietnam led to rat breeding. The US luxury tax led to the wealthy saving more money and mass layoffs in the luxury industry. Bank regulations in the wake of the financial crisis gave big banks a competitive advantage over small banks.
These aren't apples to apples examples, but they show how regulatory action often has unintended consequences due to the complexity of the real world.
