I can only guess that you're being downvoted because you want a replacement technology for the Space Shuttle. That's still a pretty divisive issue, as the some people blame the shuttle for NASA not developing new launch vehicles for 30 years, as they spent so much effort maintaining the shuttles. I think the SpaceX approach is working better, at least for now, where you attempt reusability, but not for a long time. It's like a Harbor Frieght tool -- use it like 3 or 4 times before it's toast. But SpaceX hasn't yet had the fun of launching passengers, so it's really not a fair comparison.
