Maybe it is common, and maybe it isn’t, but it doesn’t matter. Hashem loves people even if they don’t have a Rav, so I do too.
For their own sake, they should get one. It’s a mitzva d’Oraysa to attach yourself to a Rav. Plus it is nice to have a community.
But maybe we will try to avoid denigrating such people from our comfortable chairs behind our laptop screens, because they are Jews, just like us, living in Israel, and trying to do the right thing, and we do not know their stories.
