Long ago, Sasuke had already thought about what to do with Infinite Tsukuyomi in the future.
Honestly, he had always felt that Kaguya and Madara had played their cards terribly.
Using Infinite Tsukuyomi to make everyone dream together was a criminal waste of a treasure.
This thing ought to be turned into a virtual world.
Didn't Kaguya just want chakra? Catching everyone in one net wasn't the way. Sustainable draining of the pond to catch the fish was the true path.
If you sent all humanity into one big dream in a single stroke, where would their descendants come from? You would only get that one batch of chakra. It should be made into one of those trashy online games: want to get stronger? Top up with chakra.
When people slept at night, their minds would connect to Infinite Tsukuyomi and play in the Tsukuyomi World, while the chakra their bodies refined during normal rest went to Kaguya.
Each individual contribution might be small, but it would pile up over time.
And this thing could partner with the Sage of Six Paths' Pure Land.
After death, souls would be uploaded to the Tsukuyomi World. If they wanted to visit the Present World, they could follow the example of Impure World Reincarnation and descend into special White Zetsu bodies made by the God Tree.
The God Tree server's capabilities were beyond question. It was far better than a potato server.
With absolute powerhouses keeping things in check, clear rules providing guidance, and tremendous material and spiritual abundance, achieving peace would be far more reliable than with anyone else's methods.
In any case, Sasuke had discussed this virtual-world concept with Naruto, who had constructively suggested using it to resolve difficult problems. The administrative work a Hokage had to handle, for instance.
