Maybe someone can have some fun with it -- the notion of a "simplicity complex."
Creating a new psychological niche, perhaps.
Writing another "Walden," perhaps.
Giving away or getting rid of 'all' your possessions, perhaps.
Dying to live, perhaps.
One of the old Zen guys was once asked what "the middle way" meant. "It means," he said, "the extremes." Simple things are complex. Complex things are simple. Each infuses the other in ways that make wetness and water seem separate.
But in order to know this, I think going to extremes is probably necessary.
