Except for the fact that there's usually a mismatch between how your database handles data and how you want to get them back into objects. Cue: Object-relational impedance mismatch.

And while your objects become bigger and bigger and your domain more complicated, you end up relying on ORMs who keep re-creating those objects from the database with every transaction and are loading lots of data no one requested. And then you are wondering why your stuff doesn't scale.
