The racist Christopher Columbus- interfering with that utopian empire...
Yep, just what I was thinking. After the mutiny on the ship the Bounty in 1789 after leaving Tahiti, Captain William Bligh and 18 crew members were set adrift in a 23 foot launch where they had to sail 4000 miles for rescue.
Along the way almost every island the hit to looking for food and water, they were attacked by natives, even killing one crew member. So much for “open borders”. That still goes on to this day. If you land on North Sentinel Island for example near India, the natives WILL kill you.
