Nah, a motherboard with enough M.2 connectors could easily exist. Or, U.2 or OCuLink. We have already seen 1P EPYC servers with six OCULink connectors...

Sure. My point is just that whatever bandwidth you can do locally, you can also do over the network.
As a sibling comment mentions though... the cost difference would be substantial. :(
That being said, after re-reading the comment they're talking about adding multiple PCIe cards to a box to achieve 100GB/s of local total throughput.
That would be achievable over a network by adding multiple PCIe 200Gb/s network cards too. :)
