It can be said and compared to rods. You don't need a frog, jig rod and so on, but we still do it. Why, because we can. If you have the money and you take our seriously why not.
I wouldn't suggest anyone starting out fishing go buy a Skeeter, and top of the line gear, but as you get into it why not. Pay your bills first, have family time, than make room for fishing or other passions.
