When citizen doesn't get what citizen likes, citizen often cries, 'There Should Be A Law!'
In a representative republic, the citizen would lobby his representative and generate grassroots support to encourage a new law to prohibit, require, or regulate the action. ( And/or blackmail, coerce, buy off, threaten, capture, deceive... )
At what cost?
Those with the most resources often position themselves to get what they want. Those with the most sociopathic, psychopathic, and narcissistic tendencies often deceive their way into power or influence, and some would argue are more likely to over time. Look at what is happening in USA. I mean, just look.
Some would even say that 'There Should Be A Law' amounts to a lazy and selfish desire to have the force of government work on behalf of Citizen's personal preferences.
What say you?
