Wow, "purchasing a revokable license" is an insane concept. Purchase of something revokable in general feels like... not purchasing? If there was a definite time bound that's one thing, but imagine if I sell a revokable license and then revoke it a week later -- it seems like that would be allowed?

I don't mean to disagree with you, and I have basically no expertise in this area, just shocked by the whole thing.
