I have a feeling eventually we are going to drastically reduce that cost - either through just making something similar to Starship cheaper or with some new weird hybrid launch system. For non human capable launches (no worries about high g-forces for example) some type of system that just never stopped moving but went to space and back and orbited the earth continuously could be interesting. Imagine like a space plane thing that temporarily "lands" on a runway like thing that is also a giant magnetic accelerator but never actually slows down all that much. Of course we would need to find a way to reliably LOAD the damn thing while it is going that fast but I can't see that being impossible. Most of the systems we are designing now are general do it all systems - they have to be suitable for both people and other payloads.
