It's not the overhead. It's a bad habit. And eventually, it will bity you. People that tend to pointlessly quote scalars (and you see it happening not just with print, but with other function calls as well), will also quote them when the scalars happen to be refs. Oops. That's to reason to "nag" about use of quotes.

As for not using $\ = "\n", to do it right, you'd have to do it each time before a print, and do it localized, or some other part of the program might act unexpectedly.

If you don't want to type the "\n", use Perl6::Say (or whatever it is called), or use something like: 

sub printnl {print @_, "\n"}

(although you won't be able to print to a filehandle that way).
