Imagine you have this:
# main scope
$fred = 1; #global
#...
{ # outer scope 
    my $fred = 2;
    #...
    { #inner scope
        #...
    }
}

In the outer scope, you could argue you don't need local because you can theoretically assign a localised $fred to the value of global $fred with just my $fred = $fred;. But in the inner scope, local provides the only means of access to global $fred (other than referencing it by package name) because otherwise access to global $fred is blocked by the presence of outer scope's $fred.
