How surprising that carbon fiber dealers would say such a thing! lol!
Did they also mention that carbon can crack, or that prolonged exposure to the sun can weaken carbon frames too? lol!
Yes steel bikes can get rusty if you leave them out in the rain or seaspray a lot.

ALL bikes last a lot longer if stored inside at night and in winter and kept relatively clean and dry and cared for.

If you keep your steel bike protected from the elements while stored, and patch tiny nicks with paint touchup or even clear nail polish, there shouldn't be a problem. Steel bikes last for many many years if given normal common sense care.
