To the "expert": margin trading = selling something you do not own

So why the losses that can occur are yours?

Because speculation simply displaces value from the real economy to the financial sector. Bitcoin needs to gain broader acceptance by buyers and merchants to become a credible alternative to the incumbent banking system. What bitcoin does NOT need is to develop fancy speculation tools that most people do not care about.

As I said before margin trading increases liquidity at the cost of volatility. Real trade of real goods and services increases liquidity while reducing volatility.
