A lot of people don't quite understand how terrible of a material lunar regolith dust is. There's not much stuff on Earth quite like it. The Moon doesn't experience any weathering, so its all super sharp and jagged compared to how smooth even the grittiest sand is here on Earth. Its electrostatically charged so it wants to cling to dang near everything. Its highly toxic to breathe in for the same reason as miner's lung. It will work its way into every joint and seal.
