The CEO example is intended to demonstrate why "ah good, this'll make the legislature more active" may be too simple.

I'd also prefer a more practical example to argue with.

IMHO my shift on this is due to the practical examples seen over the years, legislature delegating to an agency they create, with judicial review, ends up being a good thing.

I'm honestly unaware of any unjust rule-making that ended up unfairly trampling someone, much less whip-lash back and forth.
