Yeah, like let’s put our servers in a gigantic Yeti mug. That’ll help them cool off.
Don't get me wrong, this is a stupid idea and will not work due to a huge list of issues aside from cooling (some of which you mentioned).
With that said, natural cooling is commonly understood to be very simply piping in air from the outside instead of using AC. Very efficient in Iceland, Sweden, Norway, etc.
Natural cooling, in this context, implies that he's incredibly uninformed about what happens to heat in a vacuum. As you said, cooling is a huge problem because there's no medium for the heat to transfer to (like air does on earth). From my understanding, you need to build that medium yourself (like a brick of metal or something) to take that heat which then slowly emits as infrared.
I think he thinks „space is cold, therefore we can use space cold to cool servers“
