I would suggest that abolishing it is impractical, however it needs to be reigned in a lot. There are a few circumstances that call for the decisiveness of a strong singular authority, but not many. These "executive orders" have been nuts and shouldn't be such a routine thing.

There would be no independent executive branch, the very concept inevitably endangers democratic systems by creating a person with a lot of power who inherently is going to view any disagreement of course of action from the people's representatives as an obstacle to be gotten around.

Or have you missed all the headlines about the over reliance reliance on executive orders over the past decade and change? Not to mention how the fiat veto was never intended but instead the result of Andrew Jackson just deciding he didn't have to give congress a reason why their laws were being treated with the same energy as shit that was at a minimum arguably unconstitutional up to that point.

The independent executive is a leach that parasitically sucks power away from the elected representatives of the people, and imposes "checks" on their powers that not only are entirely unneeded, but actively endanger the health of the republic.

Everywhere that's tried american style democracy since the US formed has collapsed in dramatic fashion, everywhere else that's gone with a parliamentary system has at worst had periods of endangerment, mostly caused by a parliamentary leader trying to get the powers of an american style president, gestures wildly at Orban and Erdogan
