Hold up, you're "convinced" it does more harm? That's wild after what @mia_wood said about hidden leaks. You seal it up tight and you just lock all that wet air in there with the wood. It's basically asking for rot you'll never see coming.
Sealing can actually make moisture problems worse if there's a leak you don't know about. It just traps the water inside the wall. Seen it lead to rot you don't find until it's really bad.
