I feel like you might be ignoring the possible benefits of "waiting for inspiration" on some things. Usually, when I'm procrastinating, I'm just waiting for a time when I would enjoy the work. Without that, I often don't enjoy it.
Oftentimes I'll get out of bed with an unbearable drive to accomplish a single task that I've been putting off. And when this happens, I usually feel that I am more creative, dedicated, and much faster working. When you put that together, if you are trying to maximize work speed and creativity (ignoring deadlines), this kind of procrastination is optimal.
But ignoring deadlines to maximize speed and creativity is basically a way of maximizing personal fulfillment in the work. It certainly isn't maximizing any external factors.
