There's always going to be dick heads on this planet, so removing all scarcity wouldn't just solve wars and make us all hold hands, but I imagine it would solve at least some problems.

I imagine there would always be someone to stand between the resources and the end user.

As far as a world where everything is good goes, I don't think that's possible. I think the human experience demands that we experience negativity. That's why we all react to situations in proportion to our individual history instead of humanities shared experience. IE I may get upset when my food order is wrong, while also being aware of the fact that someone just starved to death somewhere on the planet.
