Not really golden. Sounds like an annoyed teenager; it's sad because the author is smarter than that. Basically his message sounds like: "I build what I want and I don't care." Well, yes, it works, as long as you enjoy the ride and don't plan to make money off it. (You of course
can make money off the result, with some luck, if you build a useful thing.)
Most of things in the initial hate list are not useless. They just are not worth obsessing over. You don't need tons of SEO, market research, or analytics. A small but nonzero amount is still useful. That guy, for instance, used the overdose of profanities as a marketing tool to successfully get his product and his personality on the HN front page.
Mocking onboarding though is a more serious mistake. Most of your users won't "figure it out" unless you care about it well beforehand.
"Have you done market research to figure out your pricing?" is a very, very reasonable question. But likely the research for your (tiny) upcoming product should take under one hour. Looking at your competition's offers and at people's reactions along the way could give you an idea or two how to (slightly) improve your own product.
And "this whole notion that you have to build something innovative and magical" mixes up two unrelated things. Actually "innovative" is rare. But absolutely go for "magical" if you can! I see "magical" as "friction-free". Say, Docker was not very innovative but "docker run" was magical. Dropbox was famously lambasted on HN for not being innovative; still it was magical enough to be a big success. Google Wave was genuinely innovative, but it sorely lacked magic,
"You’re a startup. You’re a founder. Fucking act like it." Nope, nope. A startup is a "go big or go home" kind of deal. A founder's job is to convince VCs that the thing may go big, and do an honest effort to make it happen. But with this attitude, you're not a startup. You just have got a side project, or two. It's a completely fine thing to do. "My cushion is my consulting gig. Even if all my products tank, I’ll be fine." Good for you, sir. But this is a Wendy's.
