Because paperwork automatically prevents anything from happening to your stuff.
I wonder, do you ever listen to what comes out of your mouth?
In this case paperwork does something VERY important. It means that if something happens it’s the fault of whoever did it. No paperwork means it’s on you. We’ll go back to the dredging, if you’ve got the paperwork so ACE SHOULD know about your barrels and they hit your barrels and lose them or break their equipment they have to pay you for your stuff and fix their equipment themselves. Same scenario no paperwork too bad about your barrels and here’s the bill for the dredger.
I wonder do you even bother to think. Really, ocean floor world is complicated. Everybody that does stuff in the ocean has a vested interest in knowing what’s down there and TELLING what’s down there. Makes everybody’s life easier. Really, just a little bit of thinking would allow you to realize that.
