Newcomer / Intro why found barrels are illicit?

[Chris Simon]

#323 in Maritime, at sea; The law of salvage states that a person who recovers another person's ship or cargo after peril or loss at sea, is entitled to a reward, commensurate with the value of the property so saved.

But only in the international waters, AFAIK
In our case, it's inside a system's jurisdiction, so it always belongs to someone.

Except bees .. interestingly (???)

Random Fact #322 then; if your old bees swarm out they still belong to you, for as long as you don't lose sight of them. Once you lose track of where they are, anybody able to collect, can claim.

Hahah, really?
Poor bees!
