The parallel resonant circuit will look like a very large resistor to the RF
voltage.
Circulating current is AC current times Q, but there is none or very little
AC current.

The parallel resonance is accompanied by very high circulating current in
the choke. If you think about it, your pi-network is also a parallel
resonant
circuit with high circulating current even though it is loaded by the
antenna.
The RF choke has no such load and the circulating current is even higher.
Since
the RF choke is normally wound with small wire, smoke will soon follow.
