This feels like a strawman argument. Of course Gitlab aren't suggesting that chefs, barbers, and car mechanics are going to start working entirely remotely and transmitting the product of their work via the internet. Its pretty clear from the article that they're talking in the context of knowledge work.
Indeed. I'd further say that remote work can benefit those occupations that cannot work remotely!
If we imagine that a large percentage of the population doing work that can be done from home is doing so, there will be less traffic on the roads, more time for people to go down to their local coffee shop or restaurant to grab a bite, more real estate for non-WFH companies to rent (possibly with lower costs), or even office buildings that could be converted into habitation (and thus allowing the people whose work has physical components to live closer and lessen their commutes).
Not to mention pollution, quality of life, and a healthier society. Sure, it's not a monumental impact at a global level, but I'd count it as a positive change for the most part.
