Permission Lock

All lands observing this Law have a few permission levels:
Owner: Whoever owns this property can access it, and remove or demote the permission levels of anyone related to it any time they want. Granting access must be done if the target person is already present but stuck outside. The owner can also remodel and freely move the decorations, furniture, and anything else as they choose, regardless of weight or burden. Each container within the land can have its individual permission level changed; the default is Owner. The Owner may also Lock an item on the ground to be unable to be picked up by anyone but the Owner or Co-owner if desired.
Co-Owner: A Co-owner does not own the property, but they can access it, open any Co-owner level containers, and give Friend permission to others. They can also Lock an item on the ground to be unable to be picked up by anyone except the Co-owner, but the Owner automatically isn't bound by this.
Friend: A friend of the land can only access unprotected containers and use the land's facilities (doors, restrooms, anvils). Even moving a chair is impossible for a Friend, but at least they can get inside.
Access: Someone who has only been given Access can enter a land observing this law, but they can't even open or close a door. They can also discard their own items onto the floor, just like everyone else.
Open: No access is needed in order to enter this land, which means hostiles can get in just as easily as anyone or anything else.
