Buying and keeping
What do I actually own?
The right to publish that address while you keep it. Not land. Not a token. Not a share of the company.
You can set the name, the look, a featured world underneath, the guestbook, and a link out. That lasts while you are the keeper and the site is running.
The address number does not move. The keeper can change if someone pays 25% more. If the service ends, the licence ends with it.
