Well if you make the library directory writeable to a wider set of people it becomes easier to install something duff or nasty.

The same goes for using a sudo type mechanism.

Doing anything as root provides the chance to break all sorts of things. What if you get a module where someone has put something into the make to break your system?

OK so some of these are not likely but they could happen.
