I loathe Orange Man but the power to arbitrarily pardon any federal crimes for any reason is one of the powers of his office and Americans haven't ever seen fit to limit it. Trump is flagrantly corrupt and tries to flout the law at every turn, but he's also exposing the degree to which the American system has always just run on gentlemans' agreements and pinky swears.
A world in which we have to grant people arbitrary and unchecked power to overrule a justice system we can't trust, and can only hope they happen to be incorruptible, doesn't seem preferable.

Please list the departments and cite the executive orders creating each, because I think you will find that this is far less than half (and, unless you are using a non-standard definition of what constitutes a department in the US federal government, that the proportion is actually 0%.)
(A sibling commenter has demonstrated that the single example you provided is wrong, but its not just a poorly-chosen example.)
