I agree with you that "blind people can't use it" shouldn't be the number one argument against CAPTCHAs. Although I do believe there are quite a lot of blind people using the net with a lot of joy, there might be a lot of sites that are blind-people-unfriendly to begin with (photo sites, for instance). These could use CAPTCHAs with probably no problem for they probably don't lose customers.

The number one reason not to use CAPTCHAs should be because it's annoying to everyone. I've seen sites with blind-friendly approaches (like: What comes after: one, two, three, ...). Blind people can fill them out, yet these approaches are also annoying (at least to me).

It also seems the trend to make your images as hard to readparse as possible, resulting in images that are really hard to read, even for people with perfect sight.

Conclusion: do not use these things. Some people just are blind, like to use lynx/links, find pleasure in WWW::Mechanize, or just don't like to be challenged. Let them be.
