The easiest terrorist attack is getting a few people to rent apartments with gas across a city, leave the gas open on the stove for a day or whatever, and then simultaneously ignite.

Piping an explosive gas all over cities just seems like a generally bad idea.

Why isn't this the discussion?

No one has ever done that. But I imagine if someone does we will all need licenses for gas stoves, or have to take our cast iron pans out of our luggage when traveling, or some other dumb thing.
