For some people, even casting Forge of the Ancients or Burden of Time is considered a violation of NAPs. I limit it to the big 3 (Utterdark, Nexus, Corruption) myself.

Now, I can see that negotiating NAPs after casting to be the big point against Baalz's case here. But had he not done that, a few turns preparation wouldn't be out of place. No rule that even though someone has no NAPs anymore, that they must attack immediately.
