That's a recipe for going over your handle bars. On a fixie where you have your legs to stop the rear wheel this makes sense, on a freewheel bike you are asking to get really injured doing that. On a freewheel bike you absolutely want the brake in the back if it's the only one you have, even though it's not as efficient back there.
