Yes, good senders will still get messages flagged as spam. But the ISPs know this and they look at the complaint ratio. A complaint ratio of 0.5% or 1.0% is considered good. A complaint ratio of 3.0% is a problem.
We have one customer that's cleanest-of-the-clean (confirmed opt-in, valuable content, solid brand) sending 600k emails/day, and we see hundreds of spam reports. But their email gets delivered to the Inbox.
If you're a good actor with a solid technical setup you're still going to have an occasional delivery problem. This is why monitoring is so crucial. But you're not going to be putting out fires left-and-right, which is what it sounded like what _asciiker_ was saying he is doing.

My point being that the current blacklist-based system is broken from a "freedom of choice" perspective. The current system favors the established ESPs, as the cost of doing it yourself gets larger and larger.
