The answer to 'bad things exist' is not 'therefore nothing can ever be better'. You fix things 1 step at a time. Removing the hand of the state from the levers and dials of the value transfer system is a good thing.
Those things exist because we want them to. You call it bad that there's a government that decides I own my house and nobody else can take it. I call that a good thing. The government can already freeze your bank account with no problem, they don't need Brazil's system to do it.
