Indeed it has a lot of advantages, and no wonder, because it has been evolving for many decades. Many intelligent persons, economists, sociologists, doctors and others, were working on this scheme. If today, in the case of distant working, we were having the ability to create our own working schedule, it would be foolish to not use the knowledge. In short, even though I'm not that good at it myself, I would suggest to refrain from overworking.
I agree, I'm sure for many people a possibility of working from home was like an impossible dream in the past, and today it's reality for many of them.
The advantages are plenty:
you save on traffic(time and money);
you can eat better food at your home and it is cheaper than out too;
you can be doing your job when it's convenient to you(sometimes this factor is crucial) ...
I feel like I forgot to mention some other advantages, but you got the idea - working from home is better. Not for everyone, not always, but it's better overall. Some governments were unprepared at first, but the problem was solved in most places.
That's why I agree that COVID , however bad it was and is, has helped the world economy in advancing.
