The book was written for an introductory programming course at MIT. It is more rigorous of a book then most and may not be for everyone starting programming, but the right people will seek it out. It is also invaluable in that it teaches the programmer about programming more then languages.
Seeking things out doesn't just mean you read these things on articles or stumble upon them in libraries, it can also detail things like conversations with other people. Either way it is just an example that a guru might have a path that someone can follow that will get them somewhere quicker then a non-guru.
You're misunderstanding. I disagree with your fundamental premise, which seems to me to be that SICP will take someone from zero to hero quicker than more accessible methods.
