Ledger does not replace need for accountants.

We already have a bunch of software for ledger (that also doesn't require to burn huge amounts of energy).

Banks are ledger and if somebody like a government want to get info from that ledger it has been quite easy recently -- even Swiss banks relented and have been forced to submit information.

Accountants are people who specialize in knowing how to categorize stuff before it is put on a ledger in a way that meets requirements of local law and makes business more easy to conduct.

I don't see any possible way in which bitcoin is making this easier.

Who says it has to be easier or better? It does the work of handling transactions and keeping track of balances.

With bitcoin as a user you only have to pay a very tiny transaction fee in order to keep track of your account value and handle the transfer from one account to another. Is this better? Well you don't have to pay somebody to operate software and as long as you can access the bitcoin network there aren't any impediments to doing transactions.

But the point isn't if bitcoin is better or best or even good, just that is does the thing and doing that thing has value.
