It seems materially different to me because he doesn't appeal to any deity or authority as an unquestionable article of faith. Nor does he actually say anything about morality or sin or insist that not obeying these tenants will lead to some eternal torment. Instead what the op argues is that if you accept the postulate that long term gain is better than short term gain then you arrive at a certain set of conclusions about what is "good". Instead of advocating for Christian moralism, it explains many aspects of Christian moralism using a secular first principal. Of course the religious practices that happen to correspond with long term gains outcompeted the others. The religions which told you to maximize hedonism and minimize work died out. He takes it a step further. Religion is silent on junk food, sitcoms, video games, and any other modern "vice". The principal of long term vs short term gain can be applied equally well to modern times. The fact that many people independently feel like certain activities are bad habits, without any religious framework or persuasive argument telling them these habits are bad, seems to suggest that short term gain at long term expense is a root cause of the feeling of "vice". In other words, the feeling of "vice" is just a utility function baked into our neural network. What the OP has written is infinitely more interesting than an arbitrary list of 10 sins with no explanation of why one should obey.
