*sigh* I think you have completely lost track of the discussion. The point of fighting KXL was to prevent expansion of capacity because that will prevent expansion of production. You claimed that wasn't true...that production would go up as soon as prices rebounded.
I have now demonstrated that even when prices were high, oil companies were fighting to make a profit on tar sands SOLELY due to capacity issues and certainly weren't looking to grow production. That indicates that pipeline capacity limits WILL limit exploitation of tar sands resources even at higher price points. Which - full circle now - is why environmental groups were fighting KXL in the first place.
Understand now?
And I'm saying the envirowhackos might slow production down, but it will still eventually be extracted and sold when the prices are high enough to justify higher transportation costs.
