You will need to purchase the base game for ESO digitally in order to avoid using the disk. The "Any Race Any Alliance" entitlement may already be tied directly to your account.
I'm in the same position as @Hallothiel and so would appreciate an answer as well. I'd prefer to go disc-less when I change to ps5.
I also do not understand why I have to repurchase the base game. I own it already, why should we have to repurchase something we already own?
