It certainly has value. It just does not generally have literal monetary value that relates to, for example, what your company pays you.

Some tasks may mean you can forego equipment purchases/maintenance but you're probably not literally saving money by having someone do something for you. Which is fine! It's perfectly OK to say I don't like doing yard work and can afford to pay someone to do it for me. You're probably both happier as a result.

If we start to believe in the difference between use value and exchange value then we'll somersault our way into difficult economic theories rather quickly. It's best to, instead, say that nothing has value unless it can be purchased, a process by which value is instantaneous reified.

This belief in the invisible hand pricing everything right is silly.

The alternative (difference in use value and exchange value) is chapter 1, page 1 of Das Kapital.

We have to conclude that children, love, friendship, &c are all valueless because they do not have an exchange value ie: price.

My kid usually mows the lawn and I do the edges. It's actually pretty good outdoor time with family, and usually I find more to do out there if I'm just out there.
