Cut the sarcasm.
In your example they existed, but generally they do not have to. Try this:

$ while :; do echo hello; sleep 10; done > /tmp/dumbdumbdumb &
[1] 32595
$ rm /tmp/dumbdumbdumb
$ readlink /proc/32595/fd/1
/tmp/dumbdumbdumb (deleted)
$ cat /proc/32595/fd/1
hello
hello

See? We have an actual magical symlink that points to a non-existing 
path and yet it can still be opened.
