Internet monitoring: ethical?

[Shadowcliff]

I barely visit this site nowadays, but sometimes I see something on the news or online and I have to wonder what the FFR community thinks about it.

Topic: Internet monitoring/unwarranted search and seizure.

Argument: "If you're not doing anything wrong, then why be worried about it?"

Now, I have problems when it comes to defending myself--I can't seem to iterate my thoughts very thoroughly when in face-to-face conversation.
However, I know that there is something very wrong with the argument that I listed above. I just can't quite place it.

What are your thoughts? Answer the question: why be worried if you've nothing to hide?
