The reason money exists in the first place is to allow the allocation of finite resources. Where resources are limited but wants (and to a lesser extent needs) are not.
My understanding is that the rationale for a resource based economy is precisely what you are pointing at: distributing scarce resources under rules that are not bound by monetary rules.
The caveat going with this scenario is that a global governance, being the only alternative to the governance of a globalized finance system, is not immune to the risk of a totalitarian shift.
Its not only a problem of being authoritarian, its a problem that without price mechanism you can not distribute resources efficiently because information is local and (to the human capacity) infinite.
The Zeitgest movement just ignore this and keeps repeating that without money everything will be dandy. They have resurrected a lot of marxists economic fallacies (most of them dont even know where the ideas they repeat come from).
