Nice essay.
The "small stuff" that you mention has a function - to enable a society. If you don't shave and shower, you will look terrible, and for biological reasons people will think that you're nuts, that's you're an outliar, and expect strange things from you. It is not necessarily too bad, per se.
However, I argue that balance (some small stuff, but not too much, so you have time for important stuff) is better than being a great, smelly procrastinator.
Society can be pretty tolerant of eccentricity and a lack of personal hygiene when it's accompanied by genius. Look at Albert Einstein and even Richard Stallman.
