Let me reverse the question and ask, what do we gain by removing Anonymous Monks reply rights? Maybe some snipes and / or flames will vanish, but Nodereaper has been quite quick in removing them anyway. Other than that, there is no gain.

On the other side, what do we lose by removing the reply rights ? Quite a lot in my opinion :

If somebody posted their question anonmously, it is quite likely they will have the same reasons to post an update, clarification or anything else on that topic anonymously.

If somebody regularly reads this site, but has not felt the incentive to register for an account yet, but has something worthwhile to offer to a thread, we will lose this information because registering takes time and possibly prevents that person from answering.

Some people went into exile from Perlmonks (for a limited time) and did post anonymously - we would have lost those people.

So in my opinion, we would lose much more than we could gain by such a change.
