User "rights" are a privilege (not an elite group) used to help better the community. If a user is excessively inactive, they have no need to keep their tools because they aren't benefiting the community (and likely won't again). Inactive Admins and Bureaucrats also create a negative perception of the community's management, are extra opportunities for abuse (unmonitored accounts with higher access to the wiki), and directs community comments to dead ends (such as new users asking for help on unresponsive message walls/talk pages). These are reasons why wikis I edit have an inactive policy for Admins and Bureaucrats.

Those inactive over a year no longer need a community discussion, but it's generally a good idea to have one anyway.
