Your statement "If you cancel your account and stop playing for three months or more, then your game (not just your account) is now a useless brick and and can never be used again." is not entirely true. Yes if you cancel your CONTENT ID then after 3 months Square Enix has the right to delete that content ID which is linked to your character.
