It may look pointless to you as it seems that you missed the point. In the
mentioned setup each NIC has to have a separate wire/cable (goes without
saying, didn't explicitly mention it), administering processes check traffic,
when balancing they distribute the load/traffic of a machine to several NICs
in this machine and therefore to different wires/cables, the bottleneck issue
decreases.

Who has told BSD could do it? I have written to think of a comparison of an
other system to BSD, if BSD can't do this then it can't do it. So what?
IP isn't always a point in certain contexts.
