That may be the case for home users, but not for businesses. Let's take this 
example. Employee A has files from a given project, but Employee B doesn't 
have access to that project. Employee B is malicious, and takes Employee A's 
laptop, gets it on the network, it unencrypts itself and then takes it.

Defending against threat model allowing physical access and malicious insiders, who e.g. install a screen/keyboard capturing camera in the target office, is an entirely different ballgame, requiring multi-factor authentication, etc. --- and even those are not infallible (c.f. wikileaks).

- someone breaks into your home/office/hotel room and extracts the data: 
important to some people but not very common scenario.

This is important to most businesses.

Same argument as above. Again, we're talking about taking care of the low hanging fruit like hard disks stripped from equipment and sold on Ebay.
