The other side of this is, if an image is selling, why stop making prints? (assuming you're not utterly sick of it).
Being sick of printing an image is a good reason to limit it. I'm presently working on an order for 10 prints, which I haven't printed in over 10 years. A few of them have sold over 50 times, and I found working on them (back then) tedious. I was doing it strictly for the money. (I do admit, I'm doing this job strictly for the money, too.)Revisiting them for this job has made them fresh again, but I wouldn't want to do more than what's necessary for this order. I can see them getting stale again, and quickly.
I'm limiting my new work for a variety of reasons:
1- It is good marketing, limiting the availability.
2- I don't want to keep doing the same image, even if it turns out to be popular.
3- It allows me to follow different visual interests, knowing each project has a finite life.
I understand the stances for and against limited editions, when it comes to photography. I think it's a personal decision. The only thing I stress is, if choosing to do LE's, be consistent. Stick to your number. Don't do unlimited AP's. Be honest about how you're selling your work.
Maybe I can get rich by "limiting" them to many as I can sell. I can give them away as gifts. Demand is really high if they're free.
