The takeaway from the infographic should really be that Aaron Wall (of seobook.com) runs a business that teaches (white hat?) SEO to small business owners. It's in his best interest to make SEO seem incredibly complex, difficult, and full of dangers. Which is relatively true: effective SEO is hard to do. Wall, like any good SEO, keeps up with algorithm changes. He's a smart guy, and he's most likely figured out how to overcome all of the challenges in that infographic (for $X.XX he'll show you!). It's linkbait. And great inbound marketing.
Also, Aaron Wall is a very outspoken critic of Google. There's a post every week or two on his blog about Google's ethics (or lack thereof). It's really fascinating stuff, well worth a read [1].
