So let's summarize:

In the real world, when it's YOUR electricity we're talking about:
1. Reliability is an actual thing, so much so that you'll fork out your own money to ensure it.
2. And solar isn't even close to being economical to provide that reliable power

In the theoretical, sci-fi, fantasy world you love to pontificate about, which basically involves everyone else's electricity:
1. Reliability is irrelevant, cost is the only factor, and
2. Solar is so cheap pretty soon they'll be paying us to take it.

One set of rules for you, and a whole 'nother set for everyone else.
