Look, no offense, but I'm growing most of my family's food using permaculture techniques and selling the surplus at the local farmer's market. Just like my parents did before me and my grandparents did before them. I'm not just some internet denizen who has read some blog posts. Just because it wasn't called permaculture until Bill Mollison published his "Permaculture Manual" in 1988 doesn't mean farmers haven't used many of these principles for a very long time. In fact, this is how stable, complex natural ecosystems actually work.
