>"Then what is justice without myth?"

Justice is mankind's search for an equality that is not absurd. It has nothing to do with myth.

>"How do you explain to me what it is without some sort of narration?"

Clearly (as seen above) easily. :-)

>"Is there something inherently wrong to the idea of a myth/narration?"

Not at all. Why do you ask? Seriously, I'm curious as to what I said that makes you think I was suggesting something that... broadsweeping.

>"Money does have direct influence."

No, it only affects through the imagination. Take a moment and think about it. The coins in "your" pocket, are they still "in date" or do you want to go online to check if people will trade you something for them or tell you to take them to the bank since THEY might?

>"You can use it to influence others, purchase things, or whatever."

"Purchasing" would be a myth so... And a thing can influence without being real, just look at kids running around with towels on their backs pretending to fly and shoot beams from their eyes.

>"It may be a concept, but it affects us in real ways."

Are you talking about it itself or its concept? The concept of Superman, Zeus or Odin affects us in real life but Superman, Zeus or Odin themselves affect us only through the imagination (as fictions do).

>""Do nothing" is a bit of a stretch don't you think?"

Obviously I do not.
