5) User redirection
What is slow about handing back different answers to the same query via DNS, especially when they are pre-calculated? Seems very fast to me.
Application redirection is far, far slower. (I am assuming you are talking about something like HTTP level redirects. Did you mean something else?)
As for anycast, with your own backbone, you don't need any cooperation. Even if you don't, the cooperation you need from your providers & peers is minimal at worst. (At least relative to writing the code for, say, DNS redirection.) But anycast assumes "BGP knows best", and we all know that is not even close to the truth.
