Because this way you have a public ledger that can't be mutated without notifying the public. Not everything that blockchain gives is for the trust distributed use case. For that fact, proof of work is the only thing that is purely there because bitcoin's blockchain needs a distributed trust system.

Can't this be done with something like git?

Which is basically what a blockchain is... Just that instead of a cryptographically append-only acyclic directed graph, its a cryptographically append-only linked list.
