Dear Cs,
Think of nevuah like a flame in a fireplace. If you take it outside on a thin wick, it will go out unless you keep it enclosed from the elements. Though if you take out a coal, it would still be lit. The coal may flare up if certain forces act on it. But light an incendiary device and it will explode no matter were it goes.
Once we are back on prophecy, I would like to point out that The Chinuch in yesterday’s parsha on the mitzva of listening to a true prophet (516) writes that this mitzva applies at any time a prophet is found among us. Nothing about zman hamikdash as he writes in other places.
