If we are taught to never lift with our backs, why are there popular exercises like Romanian deadlifts and good mornings which has you specifically lifting with your back?

Answer 1

Those generally aren’t lifting with your back. The movement comes from your hips (driven by the hamstrings and glutes, mostly) while your back muscles are being used to keep your torso rigid.

That said, lifting with your back is a lot less dangerous than is commonly thought. Provided you understand how to brace. This is why things like stone/sandbag lifts, where you pretty much have to lift with a rounded back due to how low you have to get, can be done without injury.
