Well the right to exit is a momentary right and is not an easement right which is a permanent property right so in this accidental case no. The property owner of the outside square does not have to be compensated unless some damage is done to his property. But the parachuter certainly owes some compensation for the owner of the living room he crashed into. I assume since there is no need for compensation short of property damage for the outside owner that this answers the question about the ignorant or cash poor man in a scenario such as this.
The right to exit also stems from the individual parachuter’s rights to leave and is not related to the inner square owner.
And as far as compensation goes towards the outer square owner if his property is some how damaged by the exiting parachuter the liability lies with the parachuter not the inner square owner and their failure to obtain an easement. This is because why would the inner square owner have to be accountable for the mistakes of the parachuter. How would someone prepare and be liable for an accident that totally originates from another free agent.
Thanks everyone for your responses, especially yours Deist. Much appreciated!
The most interesting part of this problem is the fact that we theoretically have this same problem in the current nation-state system. If the Vatican invites me to their property and then the Catholic Church tells me to get out but Italy then refuses to let me back into the country I am stuck in the same problem. This isn’t really just a problem with absolute property rights. It’s a problem of nation-states as well.
