But I hear u on the safer lower voltages and simplicity of a low volt systems.
Thanks guys this has all made me slightly less confused 8)
30v on a 1-turn motor is identical speed/rpm range, identical efficiency, identical power output, identical torque etc as 300v into a 10-turn.

More volts will give you better acceleration and a faster top speed.
More amps will give you better acceleration but the same top speed. Although a faster speed uphill.
You can also push more watts through the same wiring at higher voltages without overheating the wiring.
Sounds like its time to re-read the thread and think of electro-mechanical devices in terms of power input.
Yes, for the same sized wire more current makes it hotter, but this is unrelated to what happens inside the motor where only copper fill% matters as everything else balances perfectly.
