Speaking of things that aren't true

> The coating is not magic, it's just oil

To say it is "just oil" is to say that breast milk is "just formula."

Yes, the cuticle has oil in it and is an oily substance, but it's a complex mixture of proteins, lipids,some of which are oily. The starkest difference of course being that mineral oil, the usual post-wash coating, would not allow the egg to remain viable, irrespective of whether it had been sanitized. It is less permable to gases than the natural cuticle, and less effective at preventing bacterial growth. As you have discovered, less effective does not mean not at all effective, and I store both my unwashed and store-bought eggs on the counter as well, but even discounting supply chain timings, the natural eggs keep longer.
