All of this doesn't matter.  The second law of thermodynamics does not 
prohibit the origin of life, nor does it prohibit the evolution of life 
over billions of years that it has been evolving on this planet.  Being 
wrong about your concepts like "neutral drift" doesn't matter because 
you can't get to where you want to go with this argument.  Just think, 
drift obviously does not have to be neutral to selection.  Drift can 
obviously decrease your concept of entropy.

Entropy is always increasing whether there is an energy capture method 
or not.  As the entropy increases it just produces something like 
molecules that can exist for a while before contributing to the 
continued entropy increase.  Entropy is increasing a lot as photons are 
captured by plants and in their efforts to make glucose.
