> You are comparing "sending a small crew for a few days on the Moon ASAP for propaganda purposes" with "setting up a permanent outpost on the Moon".
No, OP is comparing a launcher that worked reliably (it's in the history books) with a launcher which never performed a mission and is reporting "anomalies".
Many Saturn V stages blew up on test stands as well (its also in the history books) and some flight were very much on the edge of success. It was also not trying to make the whole system reusable and economicaly sustainable (just check when the last Saturn V flight was - if it was sustainable it would be still flying, right ?).
