Example 1: Killing your own grandfather, so that you're never born, meaning that you can't kill your grandfather, meaning that you're born, meaning that you kill your grandfather etc. (Mentioned in the episode IIRC and promptly ignored.)
Example 2: You find a way to send signals a few seconds back in time. You rig some C4 to the radio transceiver, and set it to explode as soon as the signal arrives. You wait a bit and send the signal back in time. The signal arrives. The transceiver explodes. The signal is not sent. The transceiver doesn't explode... (And so on and so forth...)
Stargate-style time travel leads to absurdity. This proves that it's impossible. (Reductio ad absurdum.)
(The simple fix: Alternate realities. Don't like those very much either, but a "1969 reality" would provide the exact same opportunity to put Teal'c in a funny wig.)

More importantly, there's nothing inherently illogical about finding a cure for a disease, even a super-science cure for a super-science disease from the show.
