You're not really making a point, besides "a manager is not a coding position". This article is explaining why the author thinks it should be. It's not enough to say that managers shouldn't code, you need to demonstrate that either the authors points are wrong, or that there's a greater risk by spending 30% of your time coding. FWIW, I spend probably 30% of my time coding, I manage 13 developers, and I'm capable of hiring more people. If you're not good at pushing autonomy down on your team, you'll make yourself a bottleneck and have no time left to code. If you hire great people, and trust them to make the right decisions, a lot of traditional management overhead vanishes.
