When I lose things it's almost always because I've put them in a safe place. Safe from me!

But yeah it's really about factoring in likelihood and opportunity. I think it helps to compare physical and digital spaces. If you have a CCTV system, then anyone could watch the monitors and see what's happening - however they'd have to get into the building, find their way to the secure room, log in to the system, etc. When something is online it creates better opportunity for surreptitious access and also greater likelihood in terms of the number of people who could potentially come across it. While in the physical space you might get away with having staff control access during the day and locking the door at night, online you have to have far more robust security measures to achieve the same level of safety.

So it's maybe better to say: the easier it is for you to access data, the easier it is for someone else to.
