I can think of two rationales for restricting the President's access to information.

One is plausible deniability: there's no need to expose the president personally to every misdeed everyone working for the government may have committed. Yes, that's a cynical, realpolitik type of answer that really pisses off people on HN, but it's true.

The other is simply that the President makes decisions at such a high level that low level information simply isn't helpful to him. The federal government is huge. The President can't function without hundreds of people who spend all day aggregating and summarizing information. This invests a lot of power in the aggregators and summarizers.
