That's purely artificial, it's unnecessary, this has been discussed to death. PoW is useless work. You aren't doing useful work you are randomly double SHA2ing energy back out into space just to play the lottery... oh look I found a nonce which hashes to less than the magic number, who cares, this has no material value, it's not functionally useful, it's contrived.
PoW is not fundamental to blockchain or crypto currencies.
