You have a point ( and Mnuchin to his credit ,based on reports, does care about regulatory burden and its impact ). So you are right, one is not like the other. To address your point directly, if OFAC tomorrow added MOHAMMAD JIHAD with no other information ( no DOB, no address, and so on ), you would be surprised how quickly the banks would respond.
Now note that that we are discussing a name, a commmon, but somewhat reliable, if mutable, driver of our identity. Now compare it to IP address and tell me, which one is a better predictor of who you are.
Unless, we are assuming IP is a proxy for location, which is another story.
