You are right, in short term, fusion has not much value. But in (very) long term, unlike fission, which no matter how incredible it is, is still only 'planetary-level tech', fusion is the first 'stellar-level tech' we've unlocked so far. If we ever plan to go somewhere else than Solar system, fusion is the key.
