I think the point is that it's a cost either way. It's either a money cost, an opportunity cost or both.
If you count it as part of the hobby, great. Me, I can't see how spending your entire spring and tanks full of propane is part of reloading. If you can make the money and buy the stuff in the same or less time, you're foolish not to IMHO. Some people can't, some can.
Me, if I had to cast my own bullets I wouldn't shoot at all, probably never for fun. If I had to chase down the lead AND cast my own bullets... Well, I'd probably sell my guns.
