While I strongly disagree with the author's policy goal -- e.g., to drill for oil in Arctic offshore waters -- he is at least right about one thing ---  OCSLA 12a withdrawals are, at best, only a temporary mechanism to prohibit offshore drilling.  They can be, and have been, undone by other presidents.  If Obama administration had really wanted to protect waters in Alaska, they would have designated Marine National Monuments with Antiquities Act, as some proposed.  Monuments would have been much more secure, as even the Alaska delegation knew.  But for some reason, the enviros didn't want this, and so he we are.  Unfortunately, these Obama ocs withdrawals are almost certain to be reversed. Historic mistake.
