I think you are forgetting the profit incentive.  If the oil, gas, and coal companies were allowed to keep 33% of the increased profits from shutting down half their operations during a temporary 'choke' period, and the other 66% was used to fund a bootstrapping of initial biosolar habitats-- billions of bucks to kickstart Powerdown could be raised.  The detritovore desire for ancient detritus can be used to leverage the desire of those biosolars who wish to break their addiction by powering down.  Jevon's Paradox says any excess energy saved by the biosolars will be eagerly used by the addicts anyways.  All we have to do is make the addicts pay heavily to the biosolars by a financing function of letting the oil companies profitably tighten the screws by reducing demand.  Let's find out just how inelastic energy demand really is.  Stockholders make money short-term-->no big deal, what really counts are real assets like food, water, ecosystem health.

My usual disclaimer: I am no expert, would more learned TODers please evaluate?
