First CAS (content addressable storage) is nothing new. Torrents aren't new and are basically a distribed CAS database. With a magnet link (basically a checksum) you can find those files hosted by any torrent client on the planet. So sure things are "unkillable", but depend on someone/somewhere decided it's worth storing that particular chunk. Seems strange to pair "unkillable" which depends on someone somewhere that "might" do something. Much like how IPFS was easily oversold, great you can find things hosted anywhere on the planet, but if you publish 1M files and expect to magically seem them hosted elsewhere a year later you are likely to be disappointed. I do wonder if it would be a better approach to replace filecoin or similar complex trust relationships with a simple peer to peer trading program. Something along the lines of "Lets trade 128MB", trust but verify, then watch uptime/availability. For clients up less than a month, give them the free 128MB and watch, 1-3 months trust them enough to store data with a 20x replication, 3-12 months 10x replication, over a year 5x, whitelisted peers of friends/family 3x.
