I've been wondering for a while about this.
Why do people do it? I mean, if you use an online wallet, it way safer that having it stored on a file or paper which can be stolen at any time.

An online wallet has too much security for this. Like Two-Step Verification, or a pin code, etc..
this doesn't make sense to me, when you have your wallet online (web wallet or any desktop wallet which is connected) you are at much higher risk than storing it in paper form.
how can paper be stolen? they have to break into my home and steel a piece of paper!!!
I also think in similar way that there is no comparison between paper wallet or storing a bitcoin on file. paper info can be stolen if some one knows about it where as online info can be hacked as well.
