I am not aware of a damper ever being considered a storage device.
Capacitance is equivalent to mass, Inductance is equivalent to a spring, and
resistance equivalent to a damper. Am I missing something?

Nope. But the OP, now posting as 'Polymath', had said "The same
analogy applies to springs and to shock absorbers; the spring stores
energy when stretched; the shock-absorber stores energy when
compressed. Both the spring and shock absorber will return energy at
some time and this exhibit reactance!"

But the shock-absorber stores...nothing, and can return nothing. It
therefore cannot have the mechanical equivalent of reactance, and
cannot therefore be a part of a frequency-determining mechanism. He
had failed to appreciate the property of mass - a rather fundamental
point. That is why I said he was an idiot - a claim I see no reason to
change.
