Insurance was quite a great concept back in the days when pirates invented it. It insured that if one of them lost a leg, arm or eyesight while looting another boat, their survival was secured. Nowadays, its a mandatory concept of giving some random people you dont know money. They are still pirates and use it to create new rules and fences against your freedom. If you ever need their help, they might refuse because some tiny little thing in the contract will tell so and remember, it will be legal and you would have to fight for your right. Get rid of all insurance! Nowadays everything is highly trimmed to throw as much profit as possible to a chosen few. Having a bunch of trustworty friends is the biggest insurance you can get.
