Because I am a flashoholic. Flashlights change the way that I feel. When I abstain, withdrawal symptoms set in. I don't like my world view and my life view. The world and its people are wrong. Things and places are wrong. The ills of the surface of the planet are unbearable.
Then, all of a sudden, in an instant, life is great, as soon as I am buying another flashlight. I have to have just this one more added to my collection, because it is the same size as an Olight S2 baton, but 4,000 lumens. Do I really need it? Yes, but not because it fills a gaping hole in my collection, but because when I decide Yes, the world is suddenly ok/fine. People are instantly not that evil, and some are even very, very blessed. Earth is suddenly not that bad of a place to have had my spirit take flesh. In an instant, life is something to be all jazzed up about.
But there has to be more, because tolerance sets in before too long. Next, there is a X65 in my collection that needs current, hot stuff SBT-90 emitters, instead of year 2016 XHP35 emitters that are drearily obsolete. The universe that my soul was created in is not good enough until that flashlight gets its emitters upgraded.
