That's exactly what it is. LeBron is the best player in this series, no disputing that, but the team around him isn't up to the task. The Spurs are simply a better team than the Heat, they don't have the best player, but they have a better overall team and they have played better as a unit. As for Finals MVP, no chance LeBron gets it, they never give it to someone on the losing side (has that ever happened?). As you wrote, it's a team win, but since one guy has to get singled out, I'd pick Kawhi Leonard.
