Getting to orbit is a big step. You can look at the history of SpaceX and Rocket Lab to get a grasp of what it takes -- hard to imagine a sub-orbital tourism company getting there without an injection of capital. Which, btw, is how Rocket Lab did it: they started with sounding rockets, proved that the knew what they were doing, then got a big round to go orbital.
Virgin Galactic isn’t a profitable company either. They could be, of course.
My point was that you can start with a small company with a well-defined goal and product then continue to grow the vision, as long as you remain profitable.
Yeah I don't disagree here, my point was that Blue Origin's particular goal and product bootstrapping from space tourism has already been tried and more or less failed. Whereas Musk's/SpaceX's goal is to get a Mars colony going, they started with something different than space tourism and it seems to be working out.
You could bootstrap the future of space flight simply by starting with a small profitable company.
