>Well that really depends on a) whether someone (including you) wants or needs ditches (farming irrigation? undertaker? dog hiding bone?)

You just proved the point though. It's not about how much labor was expended. If we are irrigating and I spend 20 hours digging a ditch by hand and someone spends 10 minutes using heavy machinery, they both produced the same value. Labor is independent of value.

>If someone really wants a ton of ditches, and you can dig faster and deeper than anyone else, is your labor more valuable?

Only if time and depth are a factor. It's the result that has value to the purchaser, not the labor. If said company could hire someone for half the price that does it in twice the time while still meeting the company's deadline, your labor is definitely not more valuable.
