Leumas, you still seem to be arguing from the perspective that it's supposed to be some kind of legal or at least moral guide, and that it fails if it doesn't do that. In fact it wasn't. Paul outright proposes to throw away the rules wholesale.
You have to understand that these were apocalypse believers. They believed that not only the apocalypse is right around the corner, but it (or at least the messianic age) had ALREADY begun. Ehrman has some great talks about apocalypticists back then. (And it occurs to me that I sure promote him a lot, when I disagree with his main conclusion about HJ)
It's like, dunno, if you were in Hiroshima on Monday 30 July 1945 and KNOW that in exactly one week, the bomb falls. You don't have the time to give a flip about whether Tanaka is beating up his wife, and Daisuke is sleeping with his son's widow, and Yui prostitutes herself, and Subaru actually murdered a man in the riots after the great interwar earthquake, and whatnot. Giving them rules is kinda pointless compared to getting them the f-bomb out of the city. Just follow that guy out of the city, don't worry about anything else.
THAT is the kind of subculture and attitude in which Paul happens. (That and IMHO his claiming textbook schizophrenia syndromes is probably also not helping there.)
So OF COURSE he doesn't give a flip about following the rules, he only cares about getting the message to as many people as possible. The same things that for you are a failure, for him they're not even important.
Yes ... we know that... but the believing rubes do not and think that it is a morals book as painfully evinced by them ubiquitously and incessantly telling us that without their deadbeat sky daddy and his book of
.... in 2022 we can see that this "philosophy" is an abject turpitude because it says that a slave mongering ethnic cleansing voodoo prescribing human sacrifice demanding racist bigoted bronze age tribal deity had been letting fester for millennia a grudge he had against a callow couple he made out of mud because they were beguiled into eating from the forbidden fruit of a magic tree by a walking talking snake.
