Insane? How about nonsensical? The "blow up the earth real good" goal is of the mentality of someone who watches Star Wars and decides the movie portrays real physics. Vaporizing the oceans and turning the crust into molten lava is plenty of destruction. It's also many orders of magnitude less energy than a lot of the patently unphysical proposals in the article. Equivalent mass of antimatter? You'd need a lot less than that to exceed the gravitational binding energy of planet Earth, and even that is ridiculously inefficient.

That's like the proposal to achieve AI by simulating a whole human body down to the molecules. It sounds clever to college freshmen, but it really just shows people are ignorant of the orders of magnitude of what they're discussing.
