Hopefully we run out, or no lesson will be learned.

Nah, back in early May / late April I was listening / reading up on energy. And the thing that stuck with me was, when you start hearing chatter about energy export bans, that is how you know the situation is at critical point. That it'll start generalized and unattributed but it's a way to introduce the topic into ether. You don't want to surprise people with a ban, that would be even more catastrophic. You build up to it.
