All that being said, if you carry a C02 inflator, you are right, multiple cartridges is the smart move.
On any bike, weight is weight and volume is volume, and while a pump would be a very small percentage of my commuter bike + gear, it's still something. Since a CO2 inflator has been successfully fulfilling my needs for going on 6 years straight, why carry a pump?
Pump is clunkier to carry, and/or messes up the aesthetics of my bike, adds another theft prone thing to take off the bike if I'm locking it up outside, and as easy as inflation might be with the right pump, it is guaranteed not as easy or as fast as a CO2 inflator.
All this having been said, I do occasionally carry the Bontrager equivalent of the TopPeak Road Morph when the tires of my lockup bike at the other end of a bike-bus-bike commute needs air...
