The problem is economic. Truly replacing Persian Gulf oil with more expensive oil would place us at an economic disadvantage to those nations using the cheaper oil. And the cheaper oil would be quite cheap minus the US market.
Let projects like this go through and the oil market will adjust to find some good-as-it-gets equilibrium.
That's how I see it, anyway.
Indonesia is one of the OPEC members and a major oil producer. But they look ahead and see oil production dropping, so they aren’t going to wait for it.
China is going where ever they can to buy oil, but they’ve made a judgement that making their own at $35 a barrel is better than paying $40 or $50 or $200.
