If it's a fresh server, they would have virtual dominance over gathering and crafting if they had the proper 50s. The million gil is less of a factor than having the crafts/gathering and maybe 1 combat class to farm with.
A lot if the level 50 crafted greens (as well as the materials to make them) have additional restrictions on who can craft them (like you have to have craftsmanship at x level or something like that) I heard they were changing something about stuff like darkteel ingots, rose gold nuggets, etc for launch.
