You're just completely ignoring the higher up-front cost as being one of those market forces, as though it doesn't exist.  That's wrong.  Higher up-front cost IS a significant consideration to many consumers.  And consumer choice IS a major market force.

So are things like long warm-up time before they reach full brightness (and don't try to say that completely went away -- the bulbs I bought at Costco in the last 5 years still do it).  And often whiter color temp.  And often not dimmable.  Those features matter to many people in many applications.
