How Much Would It Cost To Build The Starship Enterprise?

So you want to build the Enterprise? Well good news: according to some quick, messy, napkin math, it's possible. Kind of. The bad news? It's going to be stupid expensive. But not unfathomably so!

Since we can't predict the future, or even come close to gauging the cost of development for revolutionary new inventions or substances like warp and impulse drives, shields, and teleporters, we're going to stick to what we know. It might not make us a real Enterprise, but it's about as close as you're going to get.
