Okay, so you describe a car that is essentially magical, because there is no known source of energy that can propel a 1-ton vehicle 1000 kilometers for a buck. Then you say cheap access to LEO would be somehow revolutionary, when in fact it would just be a result of competition and technical refinement. I'll note that private space companies actually are driving down costs, but they haven't invented any revolutionary tech to do it, they just took the best of what we already had and refined it and used it a bit differently. The reason there's not some enormous boom in space travel is that there is no good reason to go there for most people.
Also, you don't mine asteroids in LEO.
At this point I'm content to declare that you simply have no idea what you are talking about, and you don't even understand this topic enough to offer examples of revolutionary technologies. You've been given plenty of examples of technological advancements, some of which are
revolutionary--strides in materials technology, biotech, and computing are at least as important as anything we did prior to the '70s. You've just staked out this bizarre position and refuse to back away from it, even though you are completely wrong.
Maybe other people want to keep arguing in circles with you, but I won't. I'm done with this.
