1. Climate- the amount of energy we need and emission of SOx and NOx reduces drastically.
2. Brain Drain- The brain drain of talented, cultural people from small towns to cities leaves those towns in a poorer quality and skews cities with higher talent. People in those small towns suffer with the lack of talent and the absence of high spenders which harm the economy of these places.
3. Rent- Companies don't need to rent in cities and save huge amount of money that they can spend elsewhere. This also stops feeding the leech that is rich, (literally) rent-seeking land-owners.
4. Time- Collectively, if remote work is the trend, you save millions of man-hours per day due to lack of commute. From individual level, one can spend the time with family, read a book, learn a new skill or whatever.
5. Family- If you have a family, remote work is much greater for you. Especially if you have kids, a baby or someone ill or old to take care to.
Remote work is such a no brainer.
