thats a cool idea as long as the cargo you drop is still retrievable or i could see people trolling pirates and boarding rendered useless by just dropping your cargo
i've mentioned this before, but cargo could easily be worth more than your ship, and is not covered by your insurance. if you get paid $10,000 to take a million dollar machine across space in your $500,000 ship, you are not gonna want to dump that because they will come looknig for you to get their money back.
