My time/value equation includes the experience of having had my luggage lost enough times that checking baggage only feels worthwhile when I'm not especially going to need whatever it is I would be checking on the other end of the trip, and in that case, why bother bringing it? I'd rather bring less stuff and be sure of having it. Saving money on baggage fees and time waiting for the loading/unloading process is a nice bonus.
