I guess I'm just with Heinlein on this one: Specialization is for insects. Interdependence is great if you can [currently] afford it. I sometimes pay someone to do something that I know I can do myself. I consider it a guilty luxury. But what's the plan if you run into hard times? When money stops magically appearing? Stop driving because you don't know how to keep your car functioning? Wear dirty, wrinkled clothing because you can't do laundry? Stop eating because you can't cook?

Being able to transform money into convenience is a great benefit of living in a modern inter-connected society. But it's only great while it lasts, and relying on always having this ability is a risky move. When my parents ran into hard times they raised and slaughtered hogs. When things got better we stopped. I don't think I'd be alive today if they didn't have that know how.
