Squatters rights just sounds funny to say, sounds so daft that it is an actual thing, it's up there with finders keepers, losers weepers.
It's old laws based on the idea that if land or property isn't being used by someone and another person builds a life there over time, someone can't just turn up and say "I don't care about using this myself but I'm going to stop you using it." They only kick in after quite some time, iirc. Ultimately, we were all squatters once. From the point of view of the King of Spain, the Falklanders are squatters because he once draw a big circle on a map and said "I own this.". But the Falklander's rightly say "nobody was living here, we turned it into a home."
Squatter's Rights are the same thing writ small. It takes a decade of occupation and "acting as the owner" for that time. It's not a casual thing that just happens.
