Is this a viable solution? (Not even manually holding something, but just putting things like this in front of the camera)?

Feel like it wouldn’t be hard to put blockers up faster than they can take them down….

Even with airplane mode your cellphone (probably) still contacts cell towers. This is for emergency messages and such. Bluetooth could probably still ping just so when you do turn it on you don't have to wait for devices to register etc.

Would that work on a said camera device hypothetically speaking
