Against a state (the ones who impose capital controls etc) every contact with the bitcoin network would give you away. It’s not really designed for privacy and even networks that are like tor have been subverted. You can’t hide from a sufficiently determined state without continuous & extraordinary efforts. If you're willing to live outside the law, bitcoin could help you do so (with difficulty). If you want to live normally, it can't help you. So I guess I'm trying to say - change the law, not the tech.
