Becuause you can not open and do a directory listing on a process but you can
on something that is presented as a file system.
The advantage is that all the heavy lifting is done in user space
and the kernel only supplies a convenient delivery mechanism.
Pipes are also a kernel supplied delivery mechanism but they are not
random access, where a file system is. Otherwise they are similar.
