Why didn't someone make it a condition of national rails TOCs operating
within the Oyster area that they accept Oyster single tickets?

Oyster post-dates most of the TOCs in the London area.

After all, they accept Oyster Travelcards, so what's the fundamental
difference?

Oyster Travelcards are the same price as paper travelcards just using a
different medium. Oyster single tickets are priced differently.
