Daniel Suelo renounced money in 2000, left his last $30 in a phone booth and walked into the desert to start a new life in Moab, Utah.
On his blog Suelo describes his philosophy: I don't use or accept money or conscious barter - don't take food stamps or other government dole.
My philosophy is to use only what is freely given or discarded and what is already present and already running (whether or not I existed).
As well as quitting cash, he threw away his passport and driving license and changed his legal name, Shellabarger, to Suelo, Spanish for soil.
Ever since then Suelo has lived outdoors, camped in the wilderness, lived in caves, stayed in communes and spent nights in stranger’s homes.
