A world with very cheap materials and energy, but not cheap intelligence, will still have conflict.
People will still have a) differences in aesthetics and b) differences in their best guess answers to moral and philosophical questions. They will almost certainly still try to accumulate all available resources in service of their ideology. No finite amount of resources will satisfy people. Risking even catastrophic outcomes (like nuclear war) could still be on the table.
Cheap intelligence is what allows you to start resolving the questions that lead to conflict in the first place, for instance by running gazillions of world simulations on gazillions of mind configurations.
