How would it solve the problem?
IPFS is not magic in that regard: if whoever is your origin disappears, then your data is likely to disappear at some point, especially if it's not super popular.
There is no free lunch: you either become your origin yourself, or you pay someone else to be.
Or you could just host it on your own devices, so long as you're okay with it only being reliably accessible so long as at least one device is up and running.
