SIMPLE HYPOTHETICAL
1. I want to build a house on my land. Reason: I live there.
2. Ancap #1 says it's actually his land. Reason: He bought it from a seller who asserted they had a valid claim.
3. Ancap #2 says it's actually her land. Reason: Her ancestors lived there a long time ago, and they were driven out by force.
4. Group of Ancaps #3 disregards all of our claims and instead intends to claim the land themselves. Reason: No reason in particular, but they have guns.
Who gets to build the house, and why? And for how long can the victor of this conflict expect to live in that house?
