It does make a lot of sense to have a permanent bag kit that would suffice for any type of riding. For commuting a few miles, I wouldn't bother with anything more than a Crank brothers mini-tool set, a set of levers and a tube, along with a small pump. I never used patches even when I was riding centuries in the middle of nowhere--a spare tube and levers, a dollar bill and duct tape and good to go.
I can't leave anything on a bike so I rarely carry a kit, but where I live, I can just take a cab home
