Imagine that tomorrow all doors disappear: in houses, banks, shops, parliaments. You put it, and it disappears again. How will the laws change, and will people become more stealing, robbing, killing, robbing?

What about aircraft and submarines?

ZZZ: Is it about it? According to the conditions of the task disappeared "doors", not "lucks".

YYY: This is the decision! Instead of disappearing doors, we knock everywhere and live on :)
