What about a law that says you are entitled to a lawyer when arrested? Or a law that says if you overpay on your taxes, the government has to make you whole?
If there was a law that said everyone must only wear blue clothes on Wednesdays, that's taken away your freedom to choose what to wear. If there's an exception to that law that says socks can be either green or blue, that's not the law granting a new freedom to wear green socks, it's a law not taking away a freedom that existed before the blue clothing law.
