I would add to the sin/idiot bin some mamils who ride with mini mini ear-ring pumps..
My pump, at a mere 16cm in length, saved a blokes RideLondon last year when it did a sterling job on inflating his tyre to an adequate pressure when his mates oversized one fell way short of the mark.

I only ever travel without pump and spare tubes when I forget I transferred to another bike the previous day (or it's a Boris bike in London
)!
. I always carry 2 tubes, puncture kit, and glueless patches, but only once have I had to use all of them, and that was to help another in distress.
