5x faster is a spectacular improvement, the launch systems we have today are not much more capable than the ones we had 30 years ago. I don’t see any reason they will be all that much better again in 30 years, even with something like Starship. The problem is the rocket equation is brutal. The more propulsion system you add to increase the speed, the more of it you have to accelerate up to the original speed before you start getting any improvement. We do have some nice advances like hall thrusters, but they don’t actually help much for heavy duty payloads like this, and there are no huge multi-order of magnitude engine efficiency breakthroughs on the horizon.
