It's a matter of #culture.
All actions you cite are (or were) perfectly acceptable in some cultures.
#Property is a cultural construct too. A concept that came from the normalization of the steal of commons fields: it was called #private because the community were privated of those fields.
Till few decades ago, in small #Italian villages, house doors were not locked: everyone was welcome in.
I saw the same in #Kenya.
Ask yourself why you joke about how injust are these things. 😉
