`ensurepip` does not "download pip for you". It bootstraps pip from a wheel included in a standard library sub-folder, (running pip's own code from within that wheel, using Python's built-in `zipimport` functionality).
That bootstrapping process just installs the wheel's contents, no Internet connection required. (Pip does, of course, download pip for you when you run its self-upgrade — since the standard library wheel will usually be out of date).
