For the love of sanity why? The moon is 770 times as far away, which means you'd need a laser almost 600,000 times more powerful than one in Low Earth Orbit to deliver the same "punch". (Lasers spread out like any other beam of light, so inverse square law applies). Your aiming mechanism also needs to be magnitudes more accurate. If you're running this off solar power, then the moon based laser is going to be out of commission half the time, and is not going to be at peak energy most of the time. Furthermore, the launch costs are going to be astronomical.

A satellite based system can be in perpetual sunlight, with the solar panels constantly at the optimum angle for energy collection. You're right on top of the target, so aiming is easier and power delivered on target is greater.

A politician opens up a large pipeline project for bids. The first guy comes and says he can build it for 20 billion dollars. The second guy comes in and says he can build it for 10 billion dollars. The third guy comes in an says "I can build it for 30 billion dollars."
"30 billion?!?", exclaimed the politician. "We've got bids that are far less expensive. Explain yourself!"
"Certainly", oozed the third guy. "Ten billion for you. Ten billion for me, and ten billion to hire the second guy to do the actual work".

At 3g, it took the shuttle 8.5 minutes to get to Low Earth Orbit. This rocket is going at 30g. If things scale, then it will take less than a minute to reach orbit. Even if it took 5 minutes, there are three stages on this rocket. The batteries need to run for two minutes, max. In other words, you don't need big heavy batteries. Small, lightweight batteries will do just fine.

I really hate summaries that conspicuously omit the only thing that's really important in the whole article.

I hate comments that say that something is "really important" but don't explain what it is.

So, which "really important" thing in the article is missing from the summary?

The technology behind this hologram.

Science is what happens when preconception meets verification.
