That's a ridiculous argument, as surveillance has a chilling effect. It's not a hard restriction of freedom, but that doesn't really make a difference, and soft restrictions are easier to hide and deny.
First, don't think that I'm supporting spying on the general population. However, I don't feel it is the information that is bad, but what governments will do with it. For example, I don't see Google doing anything bad with the data they have on me. Yes, it's an invasion on my privacy, but frankly, I don't really care. What can they do? However, I can see governments abusing the data, especially given the recent IRS scandal where the government used information to punish groups opposing the president.
As for the "chilling" aspect of it, it's only a problem if 1) You know about it, and 2) You let it.
I can't say that a secret invasion of privacy limits my freedom in any way. How could it? I had no idea. That's not to say that it won't be used to limit my freedoms later. Everyone at one point or another is against the powers in Washington. Today, it's conservatives. In a few years, it will be liberals. Libertarians scare the bejeezus out of both parties.
