It is because dns can make or break the internet literally, while
blacklists wouldn't have such an enormous impact.

Yes, and since I'm not a spammer, my out-bound smtp should be wide
open, and my ISP shouldn't be instituting this port 25 blocking
policy, simply because they have had spam coming from their network
in the past, and are now blocking out-bound smtp to anything other
then their servers, to force users to send mail through the ISP's mail
servers, so that it can be caught if it is spam, and eliminated before
it causes trouble.

I too agree that the internet should be a wide-open community where we
can just turn the knob, and walk into someone's house so to speak,
knowing that the door won't be locked. However, spammers and other
wrong-doers have ruined the internet for us, and those are the people
that should be taking the blame, not system administrators who have
identified the source of trouble coming to their systems, and have
taken precautions to make sure that this trouble won't cause them a
head ache.
