First, I think the whole "nerves don't grow back" is a misconception. Yes, once someone has a brain or spinal injury, those nerves are forever damaged. However, foreskin restoration is done through skin expansion, which means you are growing new skin, not stretching the old skin longer. The new skin grown is not just as mass of dead skin cells. This skin is living tissue, and comes with all the other structures required to keep it alive... circulatory structures, glands, hair follicles... and yes, nerves. It's the real deal. Now, if you were, say, stretching your earlobes, you would create earlobe skin, earlobe nerves, earlobe capillaries and cartilage... basically whatever stuff is in there composing the tissue you have stretched. Since we are tensing inner and outer shaft skin, the components of foreskin, what we end up with is...yes... foreskin. To me, it's a pretty simple thing.
Did you know that legs and arms can be lengthened with [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]traction[/words]? Yes, entire limbs, and that includes skin, muscles, veins and bones. Now, if one can generate a couple inches of human limb, does it seem so hopeless to recreate a few inches of foreskin?
My personal experience is that when people complain that it is never going to be perfect and so they cannot bring themselves to restore, they are just being lazy whiners and will likely never have the drive and determination to do the work. Instead of saying, I want a foreskin but I am just to lazy to do it, they come up will all kinds of lame excuses why the task, for them, is insurmountable or not worth their time. You are being honest about your feelings concerning your circumcision. Now be honest why you aren't going to restore.
