They're doing different things, is the reason.
Most commercial sats these days are for broadcast, which need to be in GEO. It's no use putting something small into GEO, since it costs so much to get there anyway. They put something big that can last a while and serve a lot of customers (lots of transponders).
Government users (NASA and academic) are doing science, like remote sensing and atmospheric sampling and things. They don't care about having 100% coverage over the US, so they can put up tiny sats that fly over every few hours, or collections of 10s or 100s or small sats that can talk to each other.
This doesn't take into account spy sats of course, those apparently need to be both big and close.
They're different means to different ends, really.
