If the compost pile is properly managed, this is not true. It just needs to be turned once every couple of weeks or so to allow aerobic bacteria to flourish. Anaerobic bacteria are what causes the bad smell. A compost pile that gets aerated once in a while does not produce any unpleasant odor.

“…requires a host of bacteria, earthworms, and fruit flies…”

The bacteria required to turn kitchen scraps into compost occurs naturally in soil. All you really need to do when creating your pile is throw a couple handfuls of dirt in there and then let the bacteria do their thing. Earthworms are not a required part of normal pile composting. Vermicomposting, of course, requires them, but a bin to which the worms do not have access will compost kitchen scraps just fine without their help. As for fruit flies, they are also not a requirement of the composting process. They are naturally attracted to some of the things that end up in a pile though, so just keep some grass clipping or leaves next to your pile and cover up any exposed fruit or vegetable matter when you add it. Problem solved.
