It depends expensive data centers, engineers and whole legal enforcement involving judges, lawyers, prosecutors, overseer, agents and jails to make public servants not corrupted. Even hiring one human are much more expensive than blockchain. Governments and banks research blockchain to reduce all these expenditure. Blockchain data can be updated with old data permanent at the same time, not a problem at all. I honestly think you're not informed enough on this topic. What you are criticizing are mostly solved now. Gov and big banks are adopting blockchain opposite to your point.
