Hard to steal at gunpoint? Who is going to refuse to hand over their keys when the choice is "Your Bitcoin keys or your life"?
All that is vs. "show me gold, shiny ohh heavy".
You see the levels of complications....
It only sounds hard if you assume I'd take an unreasoanbly incompetent approach. It's like "rape is impossible because a women with her skirt up runs faster than a man with his pants down".
This also happens with traditional banks where I live. People are kidnapped and taken to ATMs where their accounts are drained.
