I've had various non-rolling distros fall apart on all sides within 6 months. With Arch I've had one manual intervention(aka one copy-pasted command) in over a year and one minor issue where I needed to restart a service. That's amazing and something I'll gladly take in exchange for painless and straightforward setup of pretty much anything.
Not to mention with regular backups(that should be done either way) and delaying updates in critical time periods you can easily minimize the risk.
