Could you please explain why the lumped circuit approach used by many
people across the world presupposes faster than light propagation (as
I can't)?

"The failure of any lumped element circuit model to describe the real
world lies at its core inherent *presupposition*: the speed of light
is assumed infinite in the wave equation."

"Lumped element circuit theory assumes that there are no wave
interference phenomena present, that is - the currents entering and
leaving the circuit element's terminals are identical."

"In fact, lumped-element circuit theory inherently employs the
cosmological presupposition that the speed of light is infinite, as
every EE sophomore should know."

"Lumped circuit theory fails because it's a theory whose
presuppositions are inadequate. Every EE in the world was warned of
this in their first sophomore circuits course."

Give me some time and I will compose an example based on EZNEC results
for a lumped inductor vs a helical inductor of equal inductance. The
results are nowhere near the same.
