I agree with everything you've written here, and am a big fan of worker-owned co-ops. However:

It's not hard to see "do I buy the sesame or non-sesame loaf this week?" as a much more efficient method of voting and vote tallying than actually voting.

I think the most successful worker owned co-ops tend to appear to the outside world as more or less indistinguishable from a capitalist for-profit, but internally are quite different.
