When laws are dreamt up by the state, lawful interactions may require you to hand over all possessions to the ones in power...

Lawful goes not equal good or right or respect for one's ownership.

However, (local) (natural) rules and rights could state that one stays away from other's possessions, for otherwise it equals theft...

And ethically theft could be allowed "by law", but morally it will never be explainable or just or the right thing to do...
