"It is vital because the framers believed that a republic— a thing of the people—would be more likely to enact just laws than a regime administered by a ruling class of largely unaccountable “ministers.” " -Gorsuch

"Admittedly, lawmaking under our Constitution can be difficult. But that is nothing particular to our time nor any accident. The framers believed that the power to make new laws regulating private conduct was a grave one that could, if not properly checked, pose a serious threat to individual liberty. See The Federalist No. 48, at 309–312 (J. Madison); see also id., No. 73, at 441–442 (A. Hamilton). As a result, the framers deliberately sought to make lawmaking difficult by insisting that two houses of Congress must agree to any new law and the President must concur or a legislative supermajority must override his veto." -Gorsuch

That's exactly it. Whenever I criticize the existence of executive agencies, lefties will say that they've vital because they allow our government to act fast without going through all of the obstructions.
But those obstructions are the whole point. If a bill cannot pass through those obstructions, then it is not the will of the people. That's why those obstructions are there. But these people explicitly consider the will of the people to be a giant obstruction in and of itself, so I don't know why I converse with them.
