I will try one last time because I do respect your thoughts and POV:
There is a naval weapons station very close to my house. It has all kinds of military armament there, including, I assume, nuclear weapons. There is fencing and signs everywhere that trespassers will be shot. Those signs are there for public safety. We don’t leave it up to the public to decide whether or not they’re going to trespass. The decision whether or not to enter that base by climbing over the fence is not left to personal responsibility. It’s against the law, and violators will be shot, full stop. It’s not a question of libertarianism.
And that’s what I’m talking about. In the interest of public safety, close the beaches. You can’t leave this up to personal choice. People are going to die if you don’t.
