Just curious: why is /usr/bin/python not a symlink?

No. It is the number of subdirectories (it counts their ".." entries) 
plus 2 (the parent directory and the own "." entry).

Not only that, they have slightly different semantics. With hardlinks 
you can say "I want this file, no matter if someone else holds it as 
well". Symlinks say "I want the file which is referred to by there".

In the given case, however, this difference doesn't count, and I agree 
on you that a symlink would be better here.
