I see your point.
But say henry quirk steals a pack of gum from joe's desk. Joe had forgotten he had that pack of gum; he never notices. henry quirk chews the gum, doesn't get any kind of strange illness, the wrappers don't clog up the garbage system, the gum biodegrades either inside or outside henry quirk...the world goes on and henry quirk dies of lyme disease related not to gum but to a camping trip he had gone on.
Short of eternal hellfire, there are no repercussions.
