To be "cured" against one's will and cured of states which we may not regard as disease is to be put on a level of those who have not yet reached the age of reason or those who never will;

What if we could objectively state that some thing or action provably does more harm than good? For example: cigarettes? Is it tyrannical or oppressive to encourage a loved one quit smoking - or to knock away an attacker killing someone in an alley? Obviously not.

Words, for example - do not leave physical traces or lasting evidence and therefore cannot be accurately legalized without engaging in a literal slippery slope.

However, shouting at or surprising someone and giving them a heart-attack is obviously provable - given witnesses or recording. If you were recorded yelling at someone and then they commit suicide - then, that too is provable.

The ideal leadership would work to define "harm" and protect its people from objective examples (which we already do for the most part: warning labels, liability wavers, etc), while maintaining an "innocent until proven guilty" or "burden of proof" on all matters of subjective harm (ie: harsh words, accusations, harassment) (which we DONT do much anymore, sadly - court of public opinion #metoo and all that). Keep in mind, I believe the only "insults" that should be prosecuted as "harm" are those that provably result in suicide/death (ie: instigation)

The point is that with some physical objects with near universal behavior (cigarettes will fuck your shit up regardless of who you are - so would drinking arsenic for example) - we can make objective claims about physical objects and for example: keep guns away from children.

Rule of common sense doesn't need tyranny to enforce it - just proper education and standards of behavior (which we all know would be well served by replacing current leadership/methodology).

I think Mr Lewis was being a bit histrionic in his assessment - and presumes that any "good" leader would be as obsessed with controlling the lives of their citizenry as a Clinton or Mao. I feel that it would be quite the opposite.
