FWIW I was trying to convey the idea of "not rolling your own", in that instead you could just encrypt twice by using established implementations instead of rolling your own.
But as you and less_less rightly point out, it's not at all that simple for the majority of cases we usually mean (or at least wish for) when we say "encryption".
