I had a similar complaint when I first learned about the DNS. My favorite ax to grind was movies. There's something on the order of thirty squillion domains out there of the form latesthollywoodturdmovie.com. (Often because latesthollywoodturd.com was already taken, even.) You'd think, then, that it would make better use of the namespace to have them all be latesthollywoodturd.movie.com, or something. Why doesn't that happen? Because the world's population has a vanishingly small proportion of people to whom hierarchical naming structures matter, or, for that matter, even exist. For some staggeringly overwhelming percentage of the world's internets-using population, there's not even a reason for .com. It just is, and is as immutable and unquestioned as gravity. Until you can address that, playing musical chairs with DNS hierarchies is just screaming at the wind.
