+1Pretty simple. When you get a puncture, you can plug a tubeless tire, inflate it and ride on. No need to remove wheel, break bead and replace or patch a tube as is the case with tube type.
As a commuter, at least once a year I'd end up using a plug to get home from work. (DC requires rear wheel to the curb)
Pulling the wheel to get to a tubed tire on a 700 lb bike with boxes and no center stand downtown would suck. (Center stand got removed to tow a trailer and was left off)
Plus, when tubeless go flat it is usually not the instant loss of pressure and control that happens when a tube breaks.
