Gene Roddenberry imagined a society in which humans evolved beyond their base desires and where petty disagreements and conflict didn't exist - but that made for lousy drama so the writers ignored it.
But you don't even need to go that far. A Star Trek style 'post-scarcity' society is impossible because it depends on infinite free energy, FTL and perfect matter replication, none of which are allowed by modern physics. In the real world you can't just outwit the second law of thermodynamics. No matter what form AGI takes - if it ever exists at all - it won't be magical. There will always be scarcity, and where scarcity exists there will always be hierarchies of power and control because human nature doesn't change.
