Sony doesn't care about you. You don't need an internet connection to transfer files that weren't bought/created by the psv, such as movies, music, etc, and if you don't have an internet connection, you won't be buying games from psn, so you won't need to transfer them to your computer. You won't be able to backup saves without one, but otherwise, it's not really necessary. Also, someone will probably create a hacked version sooner or later.

And ahou makes a good point about internet connection. If you dont have a internet connection, then you wont buy games from the PS Store anyway.
