I think you might have missed the point being made.

The idea of property/ownership is nothing but a social contract; it's made up. It exists only as long as the people agree on there being an authority figure (government), who chooses to uphold their idea of property, keep track of what belongs to whom, and will send people with sticks after you if you mess with that. But that authority figure (government) can also decide not to uphold that idea, or deem that "your property" is actually not yours after all and take control of it - they might even send people with sticks. And the moment people stop working under/for/with the government and people with sticks stop existing, that authority figure loses all its power to define what is "property", and what belongs to whom.

As for my personal definition of property, if someone does not live there and it's not a reasonable extension of where they live, or if it's not located in those areas and they don't often make use of it, it is not their property. So you if you want to trespass someone's holiday mansion, or private forest or gardens, or a factory "owned" by one or a few people who never step foot there but make money of people who do, I certainly don't give a shit.
