Why doesn't Bitcoin use a DHT to store its blockchain? Why doesn't Bitcoin store its blockchain in a DHT, but instead makes each (full) node store the entire blockchain?

Full nodes don't even need to store the entire blockchain (bitcoin core has a pruning mode). They must process each block at least once to ensure they have the correct UTXO set, then the raw block data can be discarded.
