So if I knock on your door, tell you to get out otherwise I'll blow your house up, and you do then does that mean I legally own it?
The more proper example would be if we each owned a side of a duplex...and ojr families were free to come and go to either side. Then you start telling me what to do and I say screw it, we’ll both just stay in our houses. Put you persist in having family members positioned in my stairwell with a gun pointed at me.
