What is exactly is the point of crafting?

[Gamemako]

Crafting offers the best unrestricted (no cap, no lockout) gear upgrades in the game

That would be missing the point. You're getting your ilvl70 stuff along the way as you collect myth tomes for ilvl90, and crafted ilvl70 gear is not good endgame equipment for most jobs anyway. You're not farming dungeons for 150 hours to get full ilvl70 crafted gear, either. Like I said, some are well beyond their item level, like most accessories. Others simply are not, like Heavy Darksteel. Of particular note here is, again, Blacksmith's endgame crafts. Crafting tools aside, you ilvl55 weapons which are not worth using over GC weapons, and you have ilvl70 weapons which are a total waste to craft over farming up a Garuda weapon and moving to the invariably-superior ilvl80 relic weapon instead. Ilvl70 crafted weapons are an alternative to nothing. If you're that worried about Titan, you can buy a success for less than the cost to craft the weaker alternative.

and SE has confirmed crafted items for PvP in 2.1.

More consumables that nobody will use.

Crafting is also a good way to earn money

And do what with that gil? I have 6 million sitting around. I don't try to get more, because it has absolutely no point. I can't buy good gear; I have to farm myth tomes for it. Farming myth tomes gives more philo tomes than I know what to do with already. Just the 5 body slots and relic+1 are 3675 myth tomes, or 123 WP runs. That's 12,300 philo tomes. What the hells could you need to buy?

buy consumables

Such as? Water Ward Mega Potions, with 15-second duration and 5 minute cooldown and mind-blowing cost for an item with no use at all? Raiding food isn't that expensive -- you can afford far more than a week's worth of raiding food from your weekly myth farm already -- and since the effect will soon persist after death, it becomes even more meaningless. You could make the same argument about farming WP already. You can pull down 300 tomes and about 8000 gil in an hour, which is right around 50k/hr from selling the mats without touching a crafting job. Problem is, why bother when the gil isn't getting you anywhere?

level additional jobs

Gil does not level your jobs. Crafters do not level your jobs. I have no idea where you're going with this.

and (next week) pay for player housing.

I can't spend 0 gil on the FC house that I don't have because I'm not in a free company! Of course, were that cost only meaningful for half of the FCs out there in the first place, as they have cash and liquid assets in the billions of gil and doubtlessly will not begin to notice the price tag.

Not to mention, some people actually enjoy crafting.

I may enjoy WAR, but that doesn't mean that WAR isn't crap at endgame.
