Did you actually mean to say that traveling the world on an airplane with a backpack is not minimalist, but driving around the country in a classic VW Bug - a fossil-fueled vehicle which is considerably less efficient per passenger-mile than a passenger jet - is minimalist? That driving around on a publicly-funded, continuously-maintained network of asphalt doesn't constitute "pushing consumption off onto others"?

One eventually realizes that minimalism of any kind is a trick of the mind. Nothing is really simple, even things that aren't alive, and nothing really exists in isolation. A thing can be minimal only relative to something else, and only along a limited axis, and only so long as you don't think too deeply.

(Did I just say that Trio's classic "Da Da Da" has only one note? Oops, I lied, I didn't look deeply enough: The chorus has a background singer, and though she - it sounds like a she - is designed to be a minimalist background singer she does sing multiple notes, adding vital depth and texture and helping to make the chorus sound so awesome: It's a joke of a chorus, but it's so much more musically rich than the verse that it sounds like heaven when it arrives.)
