I get that

I don't think you got it.

They're saying the guy thinks you have roommates because you can't afford rent, not because you need someone to do chores. You make your own bed in his world, but making the bed and other domestic chores are so time consuming that you cannot work enough to make enough money to not have a roommate.

That is, he thinks if you don't have chores then you can work more, earn more, afford no roommate.

It's super out of touch as you said, but he's not suggesting roommates do your bed.
