If you don't include the economics of the business model in the evaluation, you could say exactly the same of Juiceroo. There's clearly significant demand for juice presses.
Sure, but that's because the economics of the specific way that the business model doesn't make sense is different for the two - with Juicero, they attempted to screw over the end user, while with WeWork they were trying to screw over (public) investors.
Edit: or to borrow a popular saying - with WeWork, it's not the furnished rental office stuff that is the product, it's the IPO.
Right now, based on their own data, We is selling a dollar for 60 cents to their customers. With very flexible contracts. Of course many people and companies rent from them. Just see how long that lasts when We starts needing to get actual profit from them.
