Daniel Suelo has been living without money for nine years and has a rather extensive blog and website which he updates from public libraries. I have no plans of following his lifestyle, but it is remarkable to see a man following his convictions.
Here is a sample of his writing on pilfering food from dumpsters:
Often when you are caught at a dumpster by store owners, you are treated with contempt. What is contemptible and inexcusable is the waste, and what is both contemptible and ridiculous is locking up your waste (called anal retention) to keep hungry people from eating, and having the gall to act self-righteous in the process. This is mental illness, institutionalized and whitewashed. Notice how they almost always tell you it is "for your safety". Notice that tyranny in all its forms all over the world is almost always done "for your safety", "for your security". The corporate tyrant is turning the tables to look like the compassionate one, the intelligent one. The tyrant is telling you you are not smart enough to take care of yourself. Simply because the tyrant is a have and you are a have-not somehow makes the tyrant worthy to treat you like a child, when in actuality it is the tyrant who is living in ignorance and needs educating.
