Faced with some lawn repair, I once joined the lawncare subreddit. It was an intense echo chamber of lawn adjacent neuroticism - stress over chemicals, mowing heights, quite a few people angry at their neighbours for foolishly trying to do them a favour by cutting some of their grass (inevitably too short or tall), and a fetishisation of the "perfect" lawn - cut short with visible stripes and no other vegetation.
I definitely like lawns - they're great for running about on, playing games, having a picnic. But other vegetation is nice too. The beauty of a slightly wild garden is the abundance of nature - insects, birds, the scent of flowers. Lawns are a monoculture with none of that.
