Lunar dust tends to be described as a contamination problem. It is also a sealing problem, and that matters economically.
Every interface exposed to repeated transfer, repair, docking, or enclosure cycling depends on a seal that can keep performing despite abrasion, residue, and maintenance delay. When that trust degrades, the penalty is not only replacement cost. It is slower work, more inspection, more isolation procedures, and tighter tolerance around everything the seal touches.
This is why dust seals are becoming one of the least glamorous drivers of lunar operating expense. They sit below the level of spectacle, but they influence how often systems can open, close, move, and connect without creating a longer chain of uncertainty.
Moon operations will keep getting cheaper in some areas. Interfaces are not one of them yet.
