Yes there is, because one of the principles that define life is the ability to "pass traits onto offspring". This isn't possible without a medium to carry that information.
Self replicating systems do not require information. Self replicating systems that are "alive" by any definiton in the scientific literature, do.

In the same way RNA folds could catalyse RNA synthesis, other folding patterns could break down energy-rich compounds and generate nucleotides.
The one thing they need for this to work, is an enclosed reaction environment, aka a lipid-vesicle, which form spotaneously as long as there are fatty acids.
So no, the RNA world does NOT require some form of non-genetic-host-organisms. Folded RNA molecules within lipid vesicles are likely the earliest form of organised life.
