Please have your strawman back as I said nothing about the feasibility of a one-time cure. I was backing up dTal's right to say that a one-time cure would be superior, without suffering a pointless ad-hominem rejoinder that why don't they find one if they're so clever.

One-time cures may be a sci-fi dream but they are highly desirable, as anyone who needs regular/prophylactic treatment for any severe ongoing condition knows.
