Having read the book, I don't think Ferriss makes a point to get rich quick and retire early. I think the his point is to show that it's possible to blend work with pleasure and enjoy a life of semi-retirement.

In other words, Why spend your time working in a company for 50 years — waiting out the entire time so you can finally retire and start living the dream life — when it's possible with today's technology to run a business while visiting the very places you dream of?

Furthermore, one of Ferriss's stepping stones to living such a life is using the tools available to us to ensure that the time we spend working is put toward something meaningful. If you're a photographer, and it's your mission to be creative and photograph things, why waste time answering phone calls, setting up appointments, and tracking down receivables, when those activities have nothing to do with photography and probably aren't what you're best at? Doesn't it make more sense to hire someone to do those things, especially when that person could probably do them more efficiently than you could? The flip-side is that, when properly connected, an office manager could also be using technology to allow him or her to handle multiple office tasks, not from an office but from anywhere in the world.

Those are the points of the book, and I think you missed them.
