I'm glad the OP raised this, because I have long wondered why people want to be told what chords to use. From this thread, I now do understand, more or less.

But I agree with the comments about different people making different choices and having different needs. For a start, will the performance be better for having an accompaniment at all, and if so should that be chordal or something else?

If the person making the request is actually seeking to copy the sequence used by a particular performer, is that because they are copying the whole performance? If so, maybe they should think again. Why reproduce what someone else already does (or did at some past time)? By all means take it as inspiration, but there's no need to imitate (unless for purposes of demonstration).

Certain standard instrumental pieces may have specific chord sequences that are always used, but a folk song generally doesn't have a single "right" sequence, with anything else being wrong.

Someone who wants to use chords, but hasn't the ability to choose chords that are at least adequate to fit a given melody, probably also wouldn't know how to transpose to the corresponding chords for a different key if the original key is unsuited to their voice.
