My old friend Jacob Bernoulli disagrees with you. The chord line and shape of the human arm does not enable it to function as an airfoil. Bugs Bunny cartoons and Scooby Do episodes are not suitable examples of lift generation via arm flapping. The birds do laugh at us.
All that his metaphorical arm flapping would do is eventually cause soft tissue damage in the shoulder, and possibly elbow and wrist, joints. Perhaps "cool" if you are a sadist, or even an orthopaedic surgeon interested in some work, but otherwise rather pointless.
