Congrats to Isar but I think you don't understand the scale difference here and the immensity of what it would take to be a neck-on-neck competitor to SpaceX. The orders of magnitude of launch efficiency are... starting to become staggering.

Isar is a good fallback for sovereignty and national defense! But, if Germany wants to compete with SpaceX in earnest, they will need to re-orient a large portion of their national economy around it. They are raising something like $100 billion for their launch complex in LA currently.
