The factor you are not considering is the omnipresence of corruption. Power Corrupts, and the more power you give government the more corrupt it becomes, this is born out time and time again, yet humanity refuses to learn this lesson.
The second you give government the powers you are advocating for, the people in government start thinking of all the different ways they can "help society", this amount of power is incredibly corrupting and can not be resisted, thus it always ends badly. ALWAYS
