I mean there's degrees of temptation. I don't think that simply being in the ring's presence was generally portrayed to be an insurmountable temptation. Some situations were specifically mentioned as causing the ring's power over a person to increase (eg length of time someone used the ring would put them more under its temptation) so I don't see why it's so hard to believe that someone could send off the ring bearer. In any case if that's an issue for you, how do you get around other more fundamental issues, such as how eg Aragorn manages to escape the temptation?
