Why not use just the following two lines?

Because the two-liner doesn't do what input() does. Testing it at the interactive interpreter gives me:

The output isn't displayed until the input is entered, and then the prompt messes it up.
Admittedly this isn't likely to be an issue if you're redirecting to another file, but it demonstrates that your suggested replacement is not equivalent to the feature request.
There's no support for arrow keys, even when readline is available:
My name^[[D^[[C^[[D
This falls to me in the category "not every two lines of the code should be added as a builtin".
The built-in already exists. This is making it more useful, just like adding file to print made print more useful.
