> More broadly, the Supreme Court has made clear that the Constitution imposes important limits on Congress’s [and the President’s] ability to influence or control the actions of officers once they are appointed.

Improved on that, just a tad, for this discussions context. Not disagreeing.

Without that balance Congress couldn’t delegate anything with any expectation of its will being carried out.

And the President couldn’t ensure the agency acted competently and with respect to the President’s good faith understanding of the agency’s guiding laws.

With the courts ready to step in to settle any differences.

Agencies can only work reliably with the differing participations and limitations of all three roles.

As with all expressions of law.
