Because it *is*.  The system is starting freeradius for you.  It's
running.  You've seen that it's running.

But now you want to start it *again*?  Why?  What's wrong with the one
that's currently running?

If you want to change the options that it uses, or something like that,
then you should configure the service so that it starts with the options
you require.
