Yes for the most part. I would always want to keep some kind of security handle on my horse just in case of a spook. I teach my horses to lead so that they walk with no pressure on the lead rope and to ground tie. However, my horses will also follow me around when I have nothing on them or I can lead them with simply my hand on their poll. It just takes practice and a pretty calm horse (I wouldn't want to let go of a hot or jumpy horse).
And by the way, the only dumb question is the question that goes unasked.
