These posts bug me. What in the world do you know about "people" and their needs?
I use my M1 Air at work, when I'm at my office, it's in clamshell mode. I just take the laptop out of my bag and connect it via one USB-C cable, and I'm ready to work. When I'm out in the field, or at home, I have a laptop with a good screen and keyboard to use.
How on earth would it be easier for me to use two machines? And my employer - is it reasonable to assume that they will hand out two computers? To all employees? Two machines to buy, configure and support?
You have an opinion and a specific use case - and that's perfectly fine. But nobody's interested in you telling everybody how they should do stuff.
Simples.
