I agree; I love the idea in theory, and your points are all good ones -- and that's probably part of the reason OSS Tax software doesn't exist. And the fact that it doesn't exist is a bonus for Quicken/QuickTax and probably convinces some people not to look at GnuCash.
however, if someone wrote it, I'd probably give it a whirl, and promise not to sue if there were an error :).
