You could have a currency where taxes are already built into the transfer system and the government is funded by those transfers.

Your argument is kind of like saying your paper filling system is as good as a database. With a database your don't have to be physically present like a paper filing system. With block chain you don't need permission to access the database, it is a new thing that enables more things that centralized systems used to control and rent seekers built walls around.

My income tax is automatically deducted from my paycheck, transfer taxes and VAT are automatically taken care of.

> With block chain you don't need permission to access the database

If we are talking about databases now instead of distributed ledgers (aka. cryptocurrencies), then yes I need a permission, because if I store business relevant data somewhere, I need a mechanism to ensure that only authorized parties can access it. This is doable in blockchain-based databases of course but it's much easier in a classic RDBMS or document-store (noSQL) system.

Again, these are solved problems, and "blockchain" provides no benefit over existing solutions, but impacts usability, efficiency, scalabitily and speed.

Like a consumption tax/sales tax/GST?

Yes but potentially without a bunch of people and software to prevent you from going to jail.
