Why do you think people didn't use to craft bot on FFXI compared to FFXIV?
The difference is: on FFXIV it's about having the time more than anything else (hell you can even level a craft off leves) whereas FFXI you needed money mainly so it was an actual achievement to have a craft at max level.
Just look at FFXIVpro and you'll see how many have multiple level 50 crafts. It's just about having it max level on FFXIV rather than doing something with it. So many crafters, yet there's not a lot of gear/items for sale, at least on my server.
Make stuff harder to get (so it's more expensive) and maybe crafting more simple (simple enough so people don't feel the need to bot) and you'll get rid of botters.
