The article raises good points about the need for formal societal taboos against constant work. The ideal (often violated, though) in our modern society of the "40-hour week" as a reasonable amount is one of them. Having regular times for contemplation and separation from the bustle of the world is important.
The gig economy has dangers in it. There's a liberating aspect in that people "can choose their own hours," but then that means that they have to work more to keep up with someone else who is working a few extra hours to get ahead in their own lives. It seems like the world of labor has a tragedy of the commons aspect to it, where it's in everyone's immediate individual interest to work just a little bit longer, but the end result is that everyone has to work more for the same reward. A bit like the two-income trap: some benefits, some liberation, but there's also a cost.
I do wish, though, that the article fully grappled with the issue of the 'shabbos goy.' It praises the virtues of having everyone able to participate in a time of separation from work, but then there's this practice where the conveniences of life are still indulged in by having an outsider labor for you.
