ARR Gil Cap Reduction

[Matsume]

What will prevent this from happening:

Gillionaire has 999mil gil. 900 normal players have 1 mil gil each. Gillionaire Spends 900mil gil equally amongst each player buying up all the HQ materials in the game causing short term hyper inflation. Gillionaire now has all the HQ materials on the AH + 99 milion gil. 900 normal players now have 2 mil each. ARR launches, Gillionaire still has all the HQ materials, and now 9.9 mil gil while the 900 normal players only have 200K. Normal players now want to buy HQ crafted gear that gillionaire makes. Gillionaire sells back the now transformed HQ materials to the players he bought them from for 150K each (1.5mil pre ARR); Normal Players pay 50% more than they had sold materials for cause Gillionaire controls the market and they have no choice but to buy at his prices. Gillionaire now has 9.9mil + 900x 150K (135mil). Gillionaire spends excess gil on HQ materials ensuring he maintains control of the market.

The rich get richer, the poor get poorer. Am I missing something?

The gil cap reduction looks good on paper and in theory, but then again so did those mortgage backed securities and derivatives that caused the world wide economic crisis.

Obviously, I am imagining the worst case scenario where the rich take advantage of the poor, but show me proof that this doesn't already happen?

SO, what measures will be put into effect to prevent players from doing this? I know that the morning after the official announcement on the Live Producer Letter that literally all materia were bought off the AH on my server. What's to stop them from hoarding all the HQ darksteel/gold/mythril/cobalt/electrum ore?

New items? Increase in level cap? New recipes? New base materials?
