More cushioning
More weight carrying ability
Less chance of pinch flats under heavy loads
Won't fall into cracks and grates as easy as narrow tires
Good fat tires for street riding also have pretty low rolling resistance so the added drag isn't a huge deal for a commuter.

1.8% is trivial. Totally trivial. So trivial that I won't even go in there...
