XKCD: What if you built a billion-story building?

Don't you just love 4.5 yr olds?

It is interesting the stuff you do not think about at first. Like needing so many elevators that the whole inside would be filled with elevators to varying levels. What about flushing the toilet or fire suppression? Would the weight start to deform the Earth's crust, like Hoover Dam or the glaciers? I mean the whole thing is wacky once we start talking about something that reaches to outer space.

To put it in D&D terms, assuming 10 feet per story such a building would be 1900 times the size of the Iron Tower of Dis, 47350 the size of Khin Oin, or 237000-1894000 times the height of Sharn (depending on who you go by for sharn's height) (and Sharn is itself already about 2-16 times taller than any structure ever built in the real world)

edit: fixed where I lost track of the decimal point
