Star Trek doesn't have proper time travel tech. They have to fly around the earth a few times and fling their ship into the sun or something like that, it's already insanely impractical enough that only the insanely desperate would try it.

And yes, when the world is on the line, people can get desperate, so there's nothing wrong with Picard having done it. I mean, if I recall correctly, it usually takes a lot to get to that guy... like the insurmountable level of threat a single borg cube can pose.

As for Kirk, he's a bit of a daredevil if I recall correctly, meaning desperation likely had little to do with it.
