security by only obscurity is bad. Having both is better.

For example say I have a hollowed out wall that is hidden behind a painting.

Just putting my money in the hole is bad once it’s found it’s gone but if I put my money in a safe in the hole. Well now you need to find it and break the safe and a hidden safe is objectively better than just having a safe on the floor because you need to find it first.

Sure, if there's many paintings scattered around the house of various sizes, but if there's only one painting, in your office, behind the desk, mounted to cover a safe at standing height, then you might as well hang a neon sign saying "Look Here!" next to it.
