I said "shit is free," not "all shit is free," or "all food is free." You've done nothing but ramble. My point stands. Also, food, although scare, is freely available to a large portion of humanity, and it's provided by nature. Whether we're talking about rural people in the US, or peoples throughout developing and third world nations that need to get their food from nature. We're not talking about a tiny minority of people here. Free food is freely available to most people, just not all people. Living in a city makes you dependent on other people in every conceivable way. Most people don't live in cities though...
By the way, you're not purchasing trees when you purchase a house, unless you're in an upscale neighborhood with some pretty expensive landscaping and you've got a real specialty tree that's the focus of the yard. I have loads of oak trees on my property. I can guarantee not a dime of the purchase went toward them.
Anyway, your entire argument seems to be based on my saying "all," when in fact I didn't. So why are you even arguing?
