Here's an idea. Considering its size and continued growth across platforms and time zones, what if Elite: Dangerous just had a link on the launcher saying:
Looking for PvE? Check out Mobius Mode

In it, real player's weapons and collisions do no damage to other real players.
Similar modes exist in other games today, and modes like this have been around for decades.
