Upon rereading, I agree with your assessment, but the crux of the issue is that his example of Lisa isn't so "pristine." He argues that her small business failed because her skills weren't rare and valuable. Then he says his skills are rare and valuable. A consistent argument springing from those two statements would be either a) my business won't fail because my skills are rare and valuable, or b) Lisa can't find another job in marketing (the job she held for a decade before quitting) because those skills aren't rare and valuable. He didn't make either of those arguments, instead focusing on her yoga instructor skills. It makes for a muddled post.
