"The point of an anonymous function isn't to make it not have a name, but to be able to define it where it is needed instead of referring to some specific function name in your code."

Actually, its point is to make it a value that can be referenced from any number of bindings (associations between names and values) in any number of scopes. What you're saying is just a consequence of this.

"It also fits well with the way PHP handles "pointers", by storing the name of a variable in another variable."

Which only shows the deficiency, since any such indirect reference should never refer to a name, but to a binding instead.
