I simply don't see this as an absolute as you do. Not all attempts to curry monetary advantage (even through "chance") are, by definition, "greed" or "coveting."

Sorry, I do. Gambling for money is all about possibly winning the money. If that weren't so then there would be no such place as Las Vegas and no market for casinos. It's total coveting. If it were just for entertainment than there would be entire cities built around video arcades.
