The only rifles I own with iron sights are a couple of rimfires, and they have aperture sights. At 60+ years, my eyes do not favor open sights a lot, and having used scopes for 50+ years now, I have come to the realization that there is no real situation where I cannot use a scope effectively. With proper mounts, I can sight in two scopes for one rifle, and change the scope out in about 2 minutes...one shot to verify, and I am back in business, should one scope fail or be damaged. The other option, as one poster mentioned, is to carry a second rifle as backup on your hunting trip. The last time I had a scope "failure" was in 1963, so I have come to trust optics a lot. Obviously, this means not hunting with s**t optics!! I have made shots with scopes that would have been virtually impossible with any iron sight type, so more reason for me to scope up all my hunting rifles. JMHO, Eagleye.
