I pointed that the meaning of a particular word is more general than what was assumed in the previous post. Drawing meaning from a different perspective in the example I gave as usage, reinforces my point.

In fact it would support my point even more if a third view/meaning of the same example is presented, like, some helper of the blind guy chooses to give him lift in a car, or, some rich philanthropist donating an automated AI/IoT controlled wheelchair to the blind guy, etc - in which the act of walking itself is omitted from help provided.
