That's why you are a better at what you do than policy making. You have to consider a wider perspective than your own.
WFH should not be mandatory and neither should RTO as your job allows, e.g. if you cant do what you do without the equipment at work.
The advantages of WFH, for environment, well being and economics are obvious. Companies are saving money on energy for a start. They could do that on rent also. There is ample historical precedent, if you know a Mr Smith, his ancestors very likely lived above their place of work.
I also find WFH can be sometimes lonely, but the flexibility allows me to grow relationships outside of work, I am around more for my family without a commute.
The R&D argument doesn't stand up, it's already a successful global, distributed activity.
