That's very hopeful of you... but SE should know better. They've done this experiment before and it failed.
The Zodiac weapon required HQ crafting, and people charged an arm and a leg for it. It costs millions when it came out, and to this day still costs hundreds of thousands of gill on MB. Not to mention materia costs. All you have to do is Spirit Bond some gear, but people abused those prices too. It was a rare day when Savage Might IV was less than a mil on the MB back when the Zodiac was still BiS.
If SE really is thinking people are going to be nice to one another and help each other out, then they're either incredibly foolish or blind. You don't make a system that is designed to benefit one type of player only, and then expect that player to not abuse it.
