Yes, it was a serious question. I've watched your YouTube video, and whilst it demonstrates the effect of finer microstepping on a stepper motor with a long pointer attached, I don't think it proves that finer microstepping is of any benefit on a typical 3D printer.
On my printer, using 1/16 microstepping, the resolution is about 0.011mm per microstep in the XY plane and 0.00025 mm per microstep in the Z direction. With an extrusion width of 0.3mm, finer microstepping won't provide any noticeable improvement in resolution. The moment of inertia of of the stepper motor rotor, and the mass of the bed and print head coupled with the elasticity of the belt drive, mean that it is most unlikely that there will be any improvement in smoothness either.
btw some (perhaps most) firmwares generate stepper motor pulses at irregular intervals, when the motion in the XY plane is not directly along the X or Y axis. This is a much bigger source of non-smoothness.
