It's not arbitrary at all: you just don't happen to think the goals the developers likely had are worthwhile ones. Is it necessary for a game to function? No. But it accomplishes things that can have value to the developers and indeed the playerbase, such as extending playtime, diversifying players' understanding of other classes, and also getting players to try things they might not have otherwise.

Just as one anecdotal example, I've never healed in my previous MMOs in a serious way, and would have never gave Conjurer a real, post-15-shot if Stoneskin hadn't been a cross-class skill for Paladin. SCH ended up being my main in ARR after I found the healing here to be quite different from its state in other games and is still my secondary today. If it weren't for that, I actually probably would have quit the game prior to NIN's release, and may not have returned for it.

I do agree that Provoke is problematic, as there actually is content that requires it, and it should probably either have its level swapped with something pre-15 (since both tanks require GLA 15 anyway), or WAR and DRK should have Provoke "Clones." None of the others are strictly necessary, however, though Invigorate and Swiftcast are strong enough that they could also use equivalents for the other classes.
