I'm a home-aloner and I don't see a problem with it. Of course I would never try to convince anybody to be one. It just works well for me.
I've heard that HAers should be compared to those who've been excommunicated, which are those who the Church has separated from the community of the faithful due to their public sin(s) which She does for the good of the rest of the community of faithful. If there is a Mass and sacraments you can get to, you go there, it is required.
Whether you think so or not, the Church deems it expedient for the good of the Church and our faith to physically be a part of the community of faithful, even if, as it says in Scripture, there are only two or three others, you need to be one of them.
