It was the laser that's 20 gigawatts, according to the article, which is notable because such a laser is hard to redirect.

As for the viability of holodecks... Obviously the rest of your points are still valid, but one can only hope that someday we'll figure something out, the technology being impossible/unviable right now doesn't mean it'll stay that way. And this seems to show a theoretical possibility of manipulating light mid-air in the necessary way.
