The instructions say to ignore all other rules/laws besides "no vehicles in the park" because the jurisdiction is unknown. International agreement doesn't seem like it should break through this barrier, although I understand why others may disagree.

The notion of permissions afforded by "airspace rights," even those internationally agreed, therefore cannot be used when deciding how to answer the questions in this game. Even if we could lean on that here, airspace rights actually were infinite for a very long time -- there's even a Latin phrase saying "up to Heaven and down to Hell" -- until modern air travel began.

Instead of rights/laws, we must focus only on what it means to be "in the park" by common use of the phrase. At some point you're above it rather than in it, perhaps. It may happen to be the case that people do most often think of this altitude threshold roughly equivalent to modern airspace rights, but personally I'm not so sure.
