An interesting and provocative assertion, with which I happen to
agree.....provisionally. The trouble is that grasping, or
understanding (if you'll allow a paraphrase), the principles involved
is itself a pretty slippery concept.

In a nut shell - it would soon become apparent to anyone that it is
impossible to push a length of rope along the ground, but far easier and
more effective to pull a lenght of rope.. That is the basic concept IMHO.

Best wishes,
