Imagine dropping $15k on this but not wanting to spend $800 on an electrician to properly wire a 50A circuit so you run extension cords across the room creating a fire hazard.

As for the datacenter (I’ve racked many things with A/B power) the entire point is redundancy which this defeats the purpose of since each PSU is not properly rated. Seems incredibly bizarre to me in so many ways.

Yes - often for the data centre you'd end up with something like [1] with 4x 2700W power supplies, providing redundancy and ample power at the same time. It does mean you need four 220v power feeds though.

Why is it a fire hazard if the extension cords are properly rated for this load?

Extension cords are only supposed to be used for 90 days or so, you're technically violating the NEC if you're using them in a permanent installation.
