But if someone just moves into your property why can’t police just kick them out? That’s an illegal action. If someone came into your house and started stealing your things and you call the cops on them you don’t go to court to prove those things are really yours.

Because in many locations around the world, it's not as simple as a criminal offence, it's a civil dispute, as once you have commenced "squatting", you are now an occupant, rather than a clear trespasser. Many squatters find squatting manuals online detailing the local laws and how best to approach it to maximum time available in the property.

In France once someone entered your house (and stayed a generally agreed upon 48 hours) you have no right to evict them.

Then starts a possibly very long process to have them evicted/ If they have a child you are basically screwed and won't be able to get your property back. Or you will wait months/years and get a ruin back.
