> A squatter steals an owner's property while they're away on a Summer-long vacation
Realistically, if this would happen in real life (which isn't very common, compared to proper "occupations", which this is not), the police would kick them out quickly, as it's the owner's primary resident.
No one is arguing for squatters right for other's primary residence. The division comes when you start talking about properties that are bought/owned for the sole purpose of speculation.
