As for the space, some people don't have enough of it to replicate the "designed to work" tools at home. At my office, I have a large eraseable board behind me, printers, fast coffee machines, sometimes lunch is provided, easy access to people for "quick question" (chat/email doesn't have the same responsiveness), not to mention two huge screens and way more comfortable chair than I can fit in my home space. If my company will pay me to replicate this environment (which would have to include bigger place), I'll happily move to WFH for as much as possible.
At the same time I recognize the different preferences regarding WFH and I don't want my colleagues to be the victims of "some people prefer to use the desk at work so everyone needs to RTO". I personally advocate for individual approach, because I can see that many of my colleagues work better from home - overly social office space for them isn't really better than their comfortable home.
