The article's main concern is that "decline of religiosity has probably led to increased loneliness". The loneliness concern doesn't seem to resonate with the commenters here, so I dug in to the article's footnoted references.

The gist of the references is that loneliness is a problem for old adults, and religious community helps them. Intuitively, religious communities could probably help other groups at elevated risk of loneliness (the youth, the poorly educated, the depressed, etc.) even though I don't see studies showing that they do. The article's statement that "people are lonelier than ever before" is not supported by the references (except insofar as the population is aging, and the elderly are lonelier than the middle-aged). Footnote 11 suggests increasing social isolation across society but is, imo, not conclusive. Footnote 15 explicitly asks "Are we getting lonelier?" and finds the results inconclusive.

On the whole, it seems consistent to say "I'm not lonely right now, but I think that more diverse, intergenerational communities would be good for society."
