Even still, the ISP only keeps logs of what URLs you visit and as far as I know they are almost never mined in any way that correlates to your identity. At the worst it is like someone knows all of the addresses I go to in real life, which is still way way less knowledge than private messages to friends and colleagues or the contents of my email, or even what friends and colleagues I am contacting. Actually, it's even less than that because going to gmail or secure.google.com indicates exactly nothing to the ISP about your behavior, for pages like that it would be like someone having knowledge that you are a member at the local library without knowing what books you have checked out; hardly the most privacy infringing knowledge possible. Additionally I naturally access the internet from at least 3 different ISPs on any given day, so even then it is still less concentrated than a single monolithic entity like Facebook. With regards to court order; literally anything can happen with a court order. You can claim that phone calls or paper letters aren't private because a court order could allow police to read their contents, but I think that is really stretching the truth.
