I think it’s important not just for the consumers benefit but also the employees working in that industry. If it’s purely a profit motive then you get things like poor wages and working conditions where the employer can use “competition” as an excuse to keep wages low and reduce overhead by not prioritizing things like safety and environmental sustainability. When people have the option of working for a crown corporation that does prioritize safety, sustainability, and good work environments then private industry has to be able to offer comparable compensation and work environments to the crown corporation. The crown corp has an inherent advantage of being able to operate in a profit neutral manner, while the private industry has to be able to actually do something better than the crown corp to be competitive.
