But considering that two NICs cost less than that cable, I'd need a
pressing reason to purchase the cable instead.

There is a perceived elegance aspect.
There is also a practical aspect the only known working and conveniently physically accessible ports are USB.

USB-Ethernet dongles would be a lot more useful in the long term than USB-Serial dongles. RS-232 had a really good 40 year run, but for general communications it was mostly obsolete nearly 20 years ago. You mentioned file transfers--I can't think of any applications where that's going to be better over a pair of USB-Serial dongles than a pair of USB-Ethernet dongles.
