This kind of shortsighted thinking has created a world of corporations that relentlessly exploit consumers, often with ruinous effects on wellbeing.
Do you believe the point of government is to protect people from harm? And, do you believe that, for example, making someone addicted to junk food and obese or addicted to their phone for 20+ hours out of their waking time per week are examples of harm?
Not everyone would answer yes to both questions. Some, like the original commenter I was replying to, believe that people should be free to destroy themselves, helped along by the external forces acting upon them.
