> How do you get a follower circuit out of a 2-terminal package?

The base of the transistor is connected to the ground return
(source) of the FET, not to its drain circuit. Therefore, it's the
current flowing in the source that drives the base, rather than
the more usual configuration of the voltage swing at the drain.
