I'd put a few signs or plaques in many languages on a large remote uninhabited tropical island proclaiming it to belong to a person with my name, my birth date, an unmistakable image of me and also stating that the named person will be inhabiting said island at a certain date in the future.
Then I would come back to 'now' and enjoy the peace and dark skies.
I know it's full of holes, but we are allowed to dream
