I see it more like that there are things you can do to make sure nobody else gets into your home, like locking the door.

If your door is unlocked, either through ignorance or negligence, it's still not right for someone else to just walk into your home and look through stuff you thought was private.

Sure, they can do it, but just being able to easily do something doesn't make it right.

You'll be surprised by the number of people who thinks if you leave your internet door unlocked then your internet belongings are free to take. There is someone in this very thread arguing that having an internet enable camera in your home turns your home into a public place.

It is also funny, and depressing that many of the same people who think might makes right on the internet ends up lamenting how fucked up life is in their low trust societies, when their mindset is exactly what makes a high trust society — you know, the ones where people don't lock doors — impossible.
