You can't just transfer money however you like, even if you had complete control of the blockchain. Transactions still need to be signed by the private key of the wallet involved. You could put a transaction with an invalid signature into the blockchain, but then the chain would be rejected by clients because of the invalid transaction.

The clients could be rewritten to accept the "invalid" block. That would cause a fork between the modified and unmodified clients. Like fiat currency, the only thing maintaining the definition of a legal block is the software the majority of the network choose to run.

They could indeed, but which users and companies would switch to that forked chain knowing that it's worthless? Having a lot of hashing power doesn't let you control the software that other people are running.
