This is the real salient point in this post in my opinion;

It unintentionally demonstrates the limits of individual agency to avoid legal embroilments

That is to say: it doesn’t really matter what this person puts on their website because there is a judge and a sheriff somewhere that can force you to do something that would violate the things you wrote down because the things you wrote are subordinate to jurisdictional law (which is invoked as you point out)

It’s actually pretty poetic when you think about it because the page effectively says nothing because it doesn’t have content that the license applies to

If it’s a art piece intended to show something about licensure all it does is demonstrate the degree to which licensure is predicated on jurisdiction
