And, since there's more dielectric in coax than in TP, there's more

smaller center conductor, there's more loss.

The loss at higher frequencies has nothing to do with the amount of
copper. Because of the "skin effect" lots of smaller wires will have
less attenuation than a thicker solid core.

Only when pushing many amps through a wire (as if hf-transmitters) this
might be an issue, although even then, isolation of the dielectricum is
more of a problem. Pushing 1kw through RG58U gives a nasty smell.
