Which swiss owns switzerland? Switzerland is 42000 sq km. Can you show me land deeds by owners that cover the entire area?
Well, you can start with Wikipedia: https://en.wikipedia.org/wiki/Cantons_of_Switzerland#Constit... Then, you could reach out to the Cantons and ask about individual parcels or titles. We can measure whether they have ownership by testing if they respond to trespass, maybe by constructing a building and seeing they mobilize a response. Where do you want to move the goalposts next?
You are the one who made this really odd claim, you do the homework and show me, otherwise retract your nonsense. Who is they? Unless they physically own a title to the land the building was being made on, why should they get any say? You are the one said swiss "own" switzerland, so you need to show me the sum total of all private land deeds covers the entirely of switzerland. Not your land, not your decision. And unless you can produce an actual land deed, "trespass" is completely bullshit.
