>No system promises that its actors will behave morally.
Of course not, but government allows us to reach outside the system (in some cases) and set the rules for the system. Those rules can be used to help encourage more moral behavior and discourage less moral behavior.
>Those of us who believe they should not don't see a perfect and moral market on the other side
Okay but you can see how this language:
>If that common medium is being manipulated then the market will perceive that as damage and route around it.
does begin to imply a "perfect" market right? If something is manipulated then we just route around it. That phrasing seems to hide that the real cost in "routing around" a currency is that a lot of people lose all their money.
>we just would prefer to exchange problems of force and authority with problems of interpersonal relationships.
This wording seems to put force/authority and interpersonal relationships on opposite sides of the spectrum but that's obviously not true. Interpersonal relationships are one of the primary methods of using force and authority.
Perhaps a more accurate representation of your views is that you would like force and authority to be only transmitted person to person?
