Because the jail break doesn't give access to the entire filesystem. Still only the existing public mount. It allows install of bin files from there.
The simplest thing is is to re-enable the Developer's USB Network access and then the entire filesystem can be accessed. Then installing is trivial. It's not impossible that someone can figure how to make a bin file that can be loaded to install an application, but that's quite difficult compared to file access to normally executable parts of the filesystem via USB networking.
Or that someone might create a bin file (or patched firmware) that allows an extra directory in the public part to be linked inside the existing "hidden" filesystem so extra applications can simply be copied via USB storage.
Archos Personal Media Player HDD and Apple iPod HDD where both dreadfully locked down. The eInk Kindles and the average Android phone/tablet are nothing like as bad, especially Android as the user is supposed to be able to install stuff.
