There should be no marketing if it's mandated. These companies should not be run for profit since having insurance is required by law in many situations.
You’re describing socialism and we are operating in a capitalist society. I’m not advocating for or against but it’s naive to make these claims about how this should just be pure, devoid of evil and provided by the state. This debate will go on until the end of days.
I am describing a socialistic policy, which I think private but mandatory for-profit insurance makes a great case for. We already have government controls in place, if we lived in a "capitalist society", there would be no such thing as a health insurance mandate. We live in a hybrid world designed for regulatory capture and corruption, with our required payments flowing straight to executives and shareholders instead of actually providing a public good.
