Because people need to be told this. Over and over again.

A highly-paid medical doctor saying "You need to eat less and exercise more to lose weight" is not unexpected. The problem is that people really want to eat crap and not exercise and still be healthy.

I (an industrial controls engineer) worked on a website for my employer's small business some years ago. I was given about 40 hours to design and implement the website to describe some 200 products that we've built over the years. Some had pictures, and some even had manuals. Most had some kind of a spreadsheet entry, but between Google (now Open) Refine and some intern hours we had a product page for each. "Magic algorithmic keyword SEO juice" was the desired strategy, such that each product page ought to zoom to the top of Google results for its search term, and I (not being a technical SEO consultant) was unable to effectively convince my boss that hiding 100 copies of the title and thesaurus-generated synonyms in white-on-white text at 0 point at the bottom of the page was not the way to do it, and that linking to it from a useful and therefore popular page would work better.

A lot of small businesses view documentation as pure overhead, to be minimized at all costs. The idea that you'd have a project manager or engineer write up the email you sent (or phone call you narrated) describing how to calibrate an XYZ blagometer, copy edit it, add some diagrams, and post it as an article or whitepaper to improve future sales is viewed as wasteful and not worth the effort.

The SEO industry is like the weight loss industry. When you hear an SEO consultant advocate creating good content, that means they're one of the good ones. If you hear them describe miracle cures, they're a hack.
