While this makes sense on a few levels, I'm not sure I want to go in and let's say I need to take out $2000 in cash for a craigslist purchase. Instead of simply getting 20 $100 bills, I end up with gulp 100 $20 bills. Extrapolate this to a place like Vegas that virtually runs on cash. Can you imagine someone winning a big jackpot and have to take 6 or 7 suitcases of money simply because they have to be paid out in $20's instead of $100's? Good in theory, not much so in practicality.
