Oh I wholly agree. The point of that was to illustrate what you have to do to enforce it properly. It’s the same as trying to force porn sites to ID their users.

As for Amazon, I have not heard anything about this and I recently did a couple of returns with no request for my license. Also, you may not be aware but stores like home depot already require ID to return items and they (with the help of a 3rd party) keep a credit file of sorts on you and uses that determine who has been abusing the return process.
