Let me guess, you are in a low cost of living area (at least relative to your income) and have a big house?
I live in NYC. Residential floor space is very expensive here. My wife and I on two tech salaries can afford a fairly large place by the standards of our area, but it's definitely not large enough for 2 adults to comfortably work from home with a toddler also running around.
For us, the optimal solution is hybrid with a schedule where on any given day one of us is wfh and one in the office.
When both of us were forced to work from home full time, we managed, but it was suboptimal and a drag on productivity. The "fruits of WFH" turned out somewhat bitter.
