Government intervention and ownership of pot shops makes no economic or social sense, yet government members will see this as a career-shaping policy for themselves. It's the same decision culture that sees no real thrust from the government to modernize policing -- politicians fear personal association with change to police services. 
And it's the same for the continuation of a separate catholic school system. These difficult issues require a commitment to the public good, yet, the culture inside Queen's Park simply does not allow for intelligent change or career risk for politicians and senior bureaucrats. It's easy to see why such bad public policy and political interference has rotted out trust in transit, infrastructure, energy, policing, housing, education and the slushy corners of government that pretend to boost economic development.
