Well...spent about half hour pruning trees last year, a few minutes shoveling wood chips, manure and emptying bags of leaves under the trees. All of 15 min or less picking the fruit. No actual costs involved except a little time and that has no monetary value where I live.
I don't blanch either...just sat and peeled and cut up the peaches while talking to family, added some sugar and let them sit a bit to make a syrup, shoved them in qt bags and into the freezer.
I don't call these things labor and they don't really have a cost to me....they are just me living the life I live. I'd no more put a cost on putting up peaches than I would in breathing each day, as both just come natural as part of my life.
