Totally respectful. I just don't see putting and short selling in the same way. I recognize they're similar, but in a put situation I buy from you a right to purchase if price falls. You agree to take that risk for a clear premium and I'll buy your asset if it falls. It's insurance. 

shorting has no real asset behind it. It's a shell game. To be clear, I also don't like naked calls and puts. They should be tangibly collatorized.

your broader point on margin is exactly right.
