The thoughts in your head, and the information you gather belongs to you and you get to make decisions about how it's used. If it helps think of it as intellectual property, or perhaps an extension of bodily autonomy in less corporate terms. It's so fundamental a right that most places only enshrine more complicated versions of it as law. Most societies now even extend that right to offer control over the knowledge you store electronically or write down and the way other people get to use "your" knowledge. When we seek to impose privacy limitations on the data that others can gather we're curtailing those rights to some extent. We're telling them there are specific things they can't know and that does limit their freedom in a very fundamental way.
