If Agile is about doing as little as possible then I do not practice Agile.
From my understanding Agile reviewed practices and ceremonies and decided that many of them were out dated or not applicable in areas where change occurred often.
The goal is to do only the necessary work with enough staff to handle the necessary tasks. If that means doing less then so be it, but it might mean doing more. Understand that it depends on each situation, organization, and environment. I am sorry that it isn't as simple as you hoped.
