Adam,
This is not a stupid question at all! The peak RF current coming off the
base of the secondary coil can easily be several amperes even for small
coils and tens of amperes for larger coils. That's why a low inductance
and low AC resistance path to ground is essential for maximum
performance. A low impedance path also helps reduce radiated
interference.
