How much weight do Executive Orders have?

 I mean beyond the merely administrative technical stuff.  They never really impressed me as having the permanence of real law and besides that they can be legally challenged.  Laws or proposed laws have to go through the cumbersome process of passing through legislative bodies first where they are then debated and discussed.  Executive orders instead give off a whiff of whimsical autocracy.  "I hereby declareth I don't like polka dot ties."  The other thing that strikes me as silly is each succeeding president can simply issue executive orders that are the exact opposite of those of the previous Administration.  Trump wants to rename the Gulf of Mexico.  I don't care if he wants to rename it the Gulf of Yonkers it has no weight with scholars or academics or meets international standards of acceptability.  How 'bout the Yucatan Peninsula?  What strikes Trump's fancy here?  Where does it end?  There's a whole bundle of Trump executive orders dealing with immigration alone that are sure to be challenged in the courts.  This is not the way government is normally run it just gives any new president a sense of ephemeral power.  It's like a make believe scepter.  Go play with your crayons.

How 'bout an executive order that declareth that henceforth and going forward there shall be no more executive orders?  Forevermore.
