Worth noting that content-addressing is not meant to help making the data itself permanent, but it does help with making the identifier of the content permanent. It doesn't guarantee that the content the ID resolves to is available, but once you have a content-addressable ID, you can be sure you'll be able to get the data as long as the data is available somewhere on the network.
