The government should be involved in regulating where there are negative externalities. Negative externalities are not - I don’t like having two cables.
Also politicians care about what the majority wants. As long as you’re part of that majority you’re fine. But if you aren’t - the last thing you want is more government power.
Businesses don’t have the ability to take away my property or liberty. The government does. Given a choice between the two, Id rather the government have less power.
