I have been trying to understand this proof from the book 'Introduction to classical mechanics' by David Morin. This proof comes up in the first chapter of statics and is a proof for the definition of torque.

I don't understand why the assumption taken in the beginning of the proof is reasonable. A note given at the end tries to give some clarification, but I can't relate these 2 points.

Please be kind to help. :)
