If a company is controlling costs by forcing people to work-from-home instead of paying for office space, it's not going to reimburse the people who it is forcing to work from home for a collab space
plus a profit margin for the operator of the collab space.
As for individuals on their own, sure, if you are permanently working from home, a collab space is great if you don't have a dedicated office—but if WFH is a permanent arrangement, why wouldn't you rent space that includes a dedicated office instead of renting the two things separately with a commute between them plus probably paying a premium for shared office space since it will probably be in a more central, and expensive, location.
I mean, assuming We’s business plan isn't to continue to rent space at a loss forever, but to eventually make a profit.
