That's assuming the warehousing robots are commodities, which they aren't and maybe they'll be in a few decades.

It also assumes the moat to warehousing isn't huge, which seems kind of silly for such huge capital investments.

The moat is definitely smaller when labor, your biggest cost, is smaller. You can finance a purchase that's much larger if you are able to make the monthly payment because you don't have high labor costs. Purchasing has an ROI, and labor doesn't.

What am I missing?

The fact that warehouses are huge and need a lot of supporting infrastructure?

[trimethylpurine]

What infrastructure? Whatever it is you're talking about isn't cheaper when you add more labor.

I have a warehouse that's one aisle 4 shelves high. And another that's much bigger.

They come in all sizes and costs.

Labor is by far the greatest of those.

I think you're guessing about things...
