This is nearly identical to a thought experiment I created on manifold markets about a real boat marina which has a sign saying "Boat Owners Only"

https://manifold.markets/Ernie/boat-owners-only-sign-correct...

78% You can go in if your boat is in this marina right now.
77% If your boat here sinks can you go in?
71% If there is a fire and your boat stored here burns up partially and is not seaworthy, can you go in?
71% If your boat is here and you contracted a spot, but all legal record of that burned in a fire, and the only one who remembers who is still alive is you, and you paid cash, are you allowed in?
69% If your boat is here and you contracted a spot, but all legal record of that burned in a fire, are you allowed in?
66% If you owned a boat which is here, but it's been molecularly exchanged for identical but different atoms by aliens, you can go in
57% Only official owners of a specific but unspecified boat located on the dock are allowed through
56% You can go in if you own a real live seaworthy boat now anywhere in the world.
56% If you privately own the company that owns the boat, you may enter
53% The dock owner is not allowed to go in, unless he is or is with a boat owner
52% If you stole a boat, parked it here with a legal berth lease contract, then left, and return, can you go in?
50% If you are a shareholder in the company that owns the boat, you may pass
50% If California becomes officially Marxist, where ownership is an exclusive right of the state, can you anyone go in at all?
50% If the 24 hour video surveillance of the marina is disabled, that invalidates that sign immediately above, creating a presumption that all the signs on the fence are false, and making it the case that only non-boat owners are allowed.
50% You can go through if you open the gate
49% You can go in if you own any kind of boat in any condition in the world, including toy boats, model boats, Lego boats, virtual boats in baldurs gate etc.
47% The gate will prevent all non-boat owners from passing. Guests and passengers must swim
46% The sign isn't about who is allowed through, it's about the contents of what's on the other side. Everything beyond the fence is a Boat Owner.
45% You can go in if you have no boat, but plan to buy one someday and have a contract for a reserved berth space
44% If you own 1% of a boat here you can go in
39% You can go in if your spouse is a boat owner
38% If you own half a boat stored here legally you can go in
34% You can go in if you own a Binary Oxidizing Acetylitic Thermometer.
34% Bonus: people who own three boats stored here can alternate sleeping arrangements so that in any seven day period they never sleep in one more than 3 days, legally?
34% This market will entirely be excluded from leagues
34% You can go in if you are a former boat owner but have converted it to a sailplane, which is here.
34% You can go in if you are a leashed dog that doesn't own a boat, but is with a boat owner
34% You can go through if you have a contracted and paid berth here.
34% You can go in if you have a berth contract but are behind in payment.
32% You can go in if you have a rental boat stored here.
32% You can go in if you are a guest of someone who is a boat owner.
31% Ghosts are allowed because they say B.O.O. (Boat Owners Only), which is the password
25% You can go in if your grandpa is a boat owner
20% You can go in if you are ex navy.

From being on that site for about a year, I learned a lot about how people think of laws, judgments, legalism etc. There isn't a consensus and it leads to lots of arguments. I personally am a lot less positive on legalism as the answer to everything, yet don't really know any other systems I feel safe with, either.
