So based on Steve's / Fox's explanation there's debris, whether from the stanchions, crowns, or outside sources getting in between which either starts or comes from fretting wear. The reason the locktite works is to reduce that friction/keep junk out but not a 100% solution because it could eventually dry/crack/scrape off. I'm guessing the solution would be 1 piece stanchion/crown/steerer tube since that eliminates all gaps that would be the source of fretting wear. How you accomplish that cheaply or at all? No idea
