Why do we have a protect button for closed questions? If the question holds answers which are highly upvoted and are most viewed, then it makes sense. But why do we provide protect links on questions which are closed and not answered? Now we cannot answer closed questions either, so why protect in this particular case?
I've come across many old questions which are closed as well as protected, but are very popular. Can't we have a feature where we cannot protect questions with no answers, or closed questions with no answers?
I guess we cannot answer on closed questions anymore, so I thought why protect when even a 100k user cannot answer a closed question, but we can debate on this as what if the question was opened again, but in this case I don't think question would re-open
