That's remarkably optimistic. But people also have guest bedrooms so that family members can stay with them, not away from them. And so that they can have part-time home offices. And simply to increase the overall value of their home investment.

I think expecting the presence of Sonder in the market to efficiently trade space with houses by obviating the need for guest rooms seems like a fundamental misunderstanding of how the housing market works, particularly why people buy houses larger than what they need or utilize.
