> The power of an executive order to control the behavior of the executive branch is untestedly unlimited.
"Untestedly" being the important part. There is no practical limit on the orders that can be issued but actually enforcing those rules on anyone outside the executive branch is a different matter. Also, you skipped over the parts of EO 2021-27505 where (a) it required declaring a (rather dubious IMHO) state of emergency, (b) the sanctions were previously authorized by Congress in the Fentanyl Sanctions Act, and (c) all the sanctions applied to "foreign persons", not citizens. There is no state of emergency, sanctions were not authorized by Congress, and you want to sanctions citizens of the United States and locally-owned businesses.
