I relish the commute as the gap between personal life and work life. It allows me time to decompress and means I'm rarely thinking about the office when I get home.
It's all about what's knowing what's best for you. If you need to get in the car and sit in traffic to decompress, you still have that option if you WFH. But just like commuting takes energy, so does getting up and decompressing in a way that is beneficial for yourself.
They were implying that separating home from work is what is best for them. Some people like to work from the office - you do not need to keep pushing WFH on everyone.
