It's a lot more than the rare exception. Count up all the lightbulbs in your house, and probably half of them get used infrequently or for just a few minutes at a time (hallways, closets, the garage, the crawl space/storage room, pantry, guest bedroom, etc).  Many people never even have to replace those bulbs at all because they last for the entire time they live in that house.  

What you're advocating is throwing out working bulbs prematurely. No, most people aren't going to do that. Ironically because (in part) that enviros and others scream at people for throwing perfectly functional products in the landfill.  I've done just that in my highest usage rooms (replaced the existing BR30 ceiling floods with LEDs), but it is a waste to discard working bulbs. That's not a "market forces" thing, that's a "don't waste" thing.

On flashlights, I've had the AA cells corrode on a few of my small LED flashlights too. That's not a result of the bulb, it's a result of the batteries.
