Why does a MOSFET have no such limit on its gate resistor?
Answer: D
With an insulator rather than a junction, the gate current is smaller than any leakage path on the circuit board, so the resistor may be as large as desired - gigohms if wanted. The threshold does not compensate anything, the capacitance stores charge rather than regulating voltage, and the channel supplies nothing to the gate. The same structural difference that makes MOSFETs static-sensitive also removes this constraint.
