... And mmap'ing a large file to operate on it is widely considered an efficent way to deal with files.

Note that even memory-mapping a file is limited to the system's RAM and virtual storage constraints.

I don't think it's limited to the RAM, is it? On a 64-bit OS, the virtual storage (memory space) is really really big. x86-64 "only" supports 256TB of a possible 16EB virtual memory space.
