I have spend a handful of days over a decade and a half researching or experimenting with my family mail server config. Given that experience can be useful professionally, even if only to understand the services you are purchasing it seems like time well spent for an individual/family to me. It depends what your focus is within the industry and how much you like to be hands on. If you are an auto mechanic you might service your own vehicle. If you sell vehicles or drive them professionally then perhaps not. It isn't like any single approach is right or any particular role is preferred.
