That's a very good point. There are certainly more examples of laws that go un-enforced to reinforce your point. For example jaywalking laws are routinely flouted with little enforcement. Likewise buggery laws are routinely ignored by law enforcement.

Along that axis, you are certainly right that it is basically the same as the president unilaterally choosing to exempt a specific multibillion dollar company controlled by a powerful foreign adversary from laws passed by congress with the intent of shoring up national security.

This insight is well received by me and I'm sure others.
