Physics based destruction

This game needs a physics based destruction option, buildings and bridges that collapse into materials if not properly supported, take out a pillar and bring down part of a roof. tnt would actually destroy things. 7 days to die has this so i know its possible. Just as an option that we could turn on or off in survival and creative mode. No more floating nonsense if you dont want it. Its realy the only gamewide function this game is missing and i think it would add a whole new layer of possibilities and fun.
