SPS vs LSP

Greetings,

I've been discussing this very article on another list, the problem with
this argument is it's not reasonable. Why would you launch everything
from the Earth for a SPS and then use lunar resources for a LSP, there
is nothing about the moon that allows you to use local materials for the
LSP but stops you from using it in orbit for a SPS. This is a loaded
argument, the most blatant straw man, build your power generator with
lunar material but do it in orbit. On the moon you need two or more
power generators for each one in orbit and then you need to have
reflectors or re-transmitters in orbit to get the lunar power to
locations on the Earth were the moon is not above the horizon and if you
need to do that, why not turn them into SPS instead. After I was shown
this article for the first time I wondered why he used such a foolish
argument against SPS, I mean it didn't take a lot to see that he was
comparing apples to oranges in order to make SPS appear overly
expensive, so I put the name of the author into Google and found that he
has written many papers and when talking about power generation he
always went to the lunar option and it seems to be something of a hobby
horse of his and like some horses he seems to be wearing blinkers, well
at lest in my opinion, which I will gladly change if anybody can give me
a good reason to.

.... In this case, 1 kg of facilities and components sent to
the moon will return approximately 1,400 times as much
energy to Earth as 1 kg of a solar-power satellite deployed
from Earth.
