RabbitMQ doesn't have all that built in at all. RabbitMQ is only an AMQP message broker/exchange/queue agent. It's hard to articulate (and probably should be done in a blog post) all the things that can go wrong, but rest assured, there are a lot of things that can go wrong with RabbitMQ AND with your worker nodes that are built on-top of RabbitMQ. Distributed workloads is a hard problem, but it is a solved problem (for most applications, there are some exceptions thought too).
