Would it be stating the obvious that mustachians tend to eschew physical goods for digital ones when it comes to things like books, movies, music, video games, and computer software since minimizing clutter and space is a big concern of a frugal lifestyle? Many people still prefer physical goods for various reasons. For instance, many books are still only available in print, and many movies are still only available on discs or even videotapes. Some people don't have reliable internet connection to obtain digital goods. Some people are wary of ownership issues and DRM issues of digital goods. Etc. But of course, the average person adopts digital goods mainly out of convenience (and sometimes cost). My local library is in a very busy part of NYC and it has a DVD/Blu-ray section that is free to borrow, and yet the place is empty most of the time. You know physical goods are in trouble when people don't want to use them even when they are free.
