Nobody is entitled to every reward in the game. You want it you work for it, directly (do the content) or indirectly (Market Board).
Those who get it from the market board in turn motivate more committed players to re-run the content to sell the reward if they can use the gil.

If Japanese servers can achieve over 40% clear rate in savage content maybe the "casuals" in the US servers need to get over it and stop making excuses.
