Very complex reasoning involved but basically being able to limit the amount someone attempts to lift from another character would be useful in a lot of circumstances.
And being able to steal 1c is just fun.
I think it's very logical that a character would be able to take just one bill from a pocket rather than the largest possible handful of cash they could manage every time, and I think this kind of change could quietly improve the quality of life for both thieves and all the other players in the game.
I also don't see how setting a limit on a value is something that would need to be restricted, this exists in other contexts and I see no problem with it at all.
