Did you just ask the luthier about getting a refret or did you say what the problem was and ask for a solution? If the latter, there might be a reason that a refret was suggested over a simple glue job.
He said that overtime the wood could change from the climate etc and that could be the cause. I think paying 2k for that particular guitar to be refreted is a bit much though. I'd rather spend that money on equipment and do it myself ?
