The analogy helped me understand, but in factorio belts are required primarily because everything takes physical space. What are real world use cases for kafka? Is it primarily if your data is too much to simply store in a db?

He covers it under the introduction "Why bother with async messaging?".

Basically in the analogy the belts are queues. Factorio doesn't require queues, but it quickly leads to problems with resource management, as you essentially have to lock the system until your item is done processing.
