> 3d positional/velocity precision. SpaceX has prove that they can reliably land on a target, usually within meters On Earth, which has GPS. On a very highly engineered landing surface. Landing on inertial guidance on soft regolith is a whole different ballgame. |

Which is not the future. Optical/lidar/positioning radio is the future, to make it closed loop (NASA’s Laser Retroreflector Array for high, lidar/optical for low altitudes).
> On a very highly engineered landing surface.
As I mentioned, we shouldn't assume the earthy landing legs are used. That would be a very silly assumption.
From what I can extract from your comment, you believe that the positioning system and landing legs are the issue, rather than the control systems. I suspect both are somewhat related: positioning system to place it over predictable regolith with some, yet-undeveloped, landing legs that need to work at 1/6th gravity.
I'm of the opinion that it's possible/solvable, as is NASA. It would be helpful if you would answer why you think it's not possible: what requirement do you see that make positioning and landing on regolith unachievable for SpaceX?
