Well the satoshi coins are like the ultimate honey pot though. Normal utxo holders don’t need to worry about a targeted attempt to brute force their keys anywhere near what is surely going on with that one. So if they do ever move, my money would be on that being the reason
Personally i’ve always sort of assumed Satoshi is “no longer with us” (based solely off a quote that is always hard to find where he said ~“i don’t have much time left”)
