This is well put and I agree with it.  The user in a single user system should 
be able to install packages and they can.  In multi-user systems it is more 
complex and it should be.  If the administrator of a multi-user system choses 
to allow all users to install packages, they can do that, but it shouldn't be 
the default.

I put this in perspective of the only multi-user system at my house, the one 
my teenagers use.  I definitely don't want them installing stuff.
