Yeah, the planning part seems to be the major culprit when designing "alternative economical systems". Anyone who would want to propose a serious "alternative to the capitalist system" - which is kind of what it boils down to - would have to figure out how to out-compete the planning efficiency of capitalism. My personal favorite would be something in the way of a Wiki-like consensus engine with "many-eyeballs" checks and balances. All planning is public, all planning can be corrected by anyone. Sabotage can be avoided by there effectively being significantly more 'reviewers' than editors or through some other mean of making sabotage harder than correction. It works for Wikipedia, why not for societal planning?
