Yes, it is reflective of the phone system. If the phone system had appropriate safe guards to prevent faking of ANI data and other abuse prevention mechanisms, robocalling wouldn’t be an issue.

I’ll leave it to others to decide if you picked a bad analogy or if you just proved the point of GP, I’ve got no skin in that game and don’t care.
