It can and can’t. Remesh is designed to add more geometry for sculpting more details or to reduce geometry with a focus on sculpting afterwards. Because of this, the results may not be good for deformation/animation. So, depending on your end result you may have something that works or you may not. With that said, doing retopo is the best way to learn if a topology will work or not. Once you have that experience then look at automating the process. In my humble opinion.
And this is from a guy who would rather rig and weight paint than do modeling.
