Not very precise with “utility” in common to this place sense.

Most often it is implied that it is about pleasure (and lack of suffering), which is rather reasonable.

But to not go too far; on a more mundane level, this philosophy can be practically opposed to consumerism: instead of obtaining utility through money through hard work, obtain utility from what you have and minimal amount of things you really need.

Going further (deeper, wider, more abstract, more qualitative) would be contrarian not only to society in general but also to some of the lesswrong opinions.
