I cannot quite figure this out. We cyclists all need more exercise for our upper bodies. The good old frame pump gives us ~90 strokes of moderate effort. The mini pump has us using our upper bodies at high RPM for a long period. Both giving us something we would otherwise have to spend money and invest time to get. (Gym equipment, club memberships ...) Instead we spend money on devices to keep those benefits from happening. (Devices that may not be faster, more effective or more reliable or even time saving.)

I wonder when I'll be needed to offer my Zephal to someone whose electric pump has died. (It's (actually they: I've had ones on every bike I've owned the past 51 years) have filled in for SIlcas ,mini pumps and CO2 so far.)
