If the cost of returning and refurbishing a rocket stage is less than the cost of building a new one then that gives a competitive advantage on price.

But space flight is a strategic competency for states so China, the EU, and even eventually Russia, will all develop reusable rockets. I suspect that launch capacity will far exceed demand and that none will make profits for a long time.

If only EU would take affordable mass space launch like the critical strategic capability it is :P
