But a steel wire can be reeled in using a reel. And if we don't include the airpump required for these origami muscles in our "muscle weight" then we don't need to include the winch weight in the case of the reeled wire.

Only counting the steel wire in the winch example is unfair in the other direction. You have to count a small part of the winch (pulley?) for it to be directly comparable.

But this is all incredibly silly, and what we all agree on is that they fail to consider the vacuum pump, valves and reinforced vacuum hoses in order to make their invention seem fancier.

The proper comparison is not with the pulley, the wire or the winch, but rather the structure holding the pulley up.
