If oil producers did respond to these very strong incentives by holding back oil from today's market, the effect would be to drive today's price up. This profit-seeking wouldn't drive the price all the way up to $200, because you have significant interest, storage, and idle capacity expenses from trying to wait around a couple of years before getting your profit. An economist would expect the end result of this  profit-seeking to be that the price today is lower than what it will be in two years by an amount that reflects these interest and other expenses, but certainly far less than the difference between $60 and $200 a barrel.
