there's a huge difference between anonymity when someone is looking for you and anonymity in general. As you've mentioned, if someone wants to track you through Tor, that's still potentially possible. But that's a completely different ballgame than "My ISP wants to track every last website I visit so they can pair that with my address/billing info to sell to advertisers". I don't think my ISP is going to go through all the hoops to find my Tor exit node, just so they can sell that to advertisers. Passive onlookers can be untrustworthy too. The shades on my windows keep people from seeing me change, but if someone really wanted to see specifically me naked, they could probably enter my house and make the shades useless. I still consider the shades useful.
