Let’s say the Ethereum main chain forks into two over contention over an EIP. You are now effectively holding two copies on it on different blockchains and can transfer them independently. Which one is “the real one”? That’s purely subjective. Just like with fungible tokens (“Bitcoin cash is the real bitcoin”) The same principles apply when just making a copy on the other chain. It’s data and signatures, the rest is just interpretation.
