because changing the permission will cause the same issue:

$ cat temporary.txt 
cat: temporary.txt: Permission denied
$ ls -l temporary.txt 
---------- 1 balbi balbi 0 Feb 19 15:37 temporary.txt
$ cat temporary.txt 
cat: temporary.txt: Permission denied
$ cat non-existent.txt
cat: non-existent.txt: No such file or directory

just a different error code is returned...
