> Of course the other way is: buy motors with (metal) gears that are close to your need - then you only need to 'transform' that motion a little bit.

Buy overpowered motors close to your need, and 'transform' them by software.

Unfortunately, that only works if weight is not a concern - direct drive applications will have worse torque/weight ratio.

This is only an acceptable option when speed, torque, weight, and volume aren't a concern.
