I think we need a safety concept for surface builds like houses, buildings and other objects.
If somebody builds a house for example in a non-safety zone and loggs off. Everyone who finds this building can destroy it because the universe is persistent.
Even if you don´t build something accidentally in a non-safety zone there has to be a way to protect your creations.
Maybe some kind of protection shield which activates when a stranger attacks the building.
How do you think about that?
