There's more than enough energy and resources to go around for humans to peacefully coexist "forever", albeit in lesser numbers than today. The civilization meta game is what ruins it, despite our best attempts to regulate that. And a global self destruct button helps massively... until it does not.
Like I replied to the other commenter, it's an unstable equilibrium. Lots of things can stay perfect forever if nothing throws off the delicate balance.
We can focus effort on maintaining this balance...but doing that requires power to be used. And just like that we are back at step one.
We can communally build up trust to such a high level that everyone can act independently to maintain balance, but this naturally creates a situation where the more trust there is, the bigger the payoff for the one who breaks it. Essentially the prisoners dilemma.
