I don't know about you, but there's nothing easy about having to boot up an IDE every 7 days to sign and re-install an app you depend on. It's just one more thing to worry about and mentally keep on top of, the opposite to Apple's convenience and smooth UX ethos.
Yes I know you can technically do this without a paid dev account, but it's practically useless because it has to be re-done every 7 days.
