I think a truly WFH world would force us to fundamentally rethink some of our common infrastructure designs. And one of those would be including multiple different offices in houses. Because most houses and apartments aren’t designed with WFH in mind.

If you have a dedicated place for work, (instead of a shared space, like a desk that you also use for your personal stuff), it helps you focus. Your brain compartmentalizes the rooms in your house, (which is why you’ll walk into a room and immediately forget what you went in there for,) so having a room that is dedicated to WFH will literally help you avoid distraction. If you try to WFH from the same desk that you play video games at, you’ll feel a constant desire to boot up a game instead of working. And inversely, if you try to play a game at your work desk, playing will begin to feel like a job. Your complaint is perfectly valid, and also so common that it would literally reshape the way our houses are designed.
