If companies like airbnb allow you to work from anywhere in the world, it means timezone is not a problem. It definitely needs some investment though.

> what is the big difference now?

What is the difference between pre-2020 full-time in-office, vs 3 day or even fully remote? Nothing, in my opinion (CEOs don't agree though). If people are productive with 3 days in office, that could have been the norm before 2020.

All you need is someone actually making it happen.
