Commercial kitchens are more rare then empty office space because they require a lot of certifications and special equipment. Also if you are cooking food for the public then it has to be done in a commercial kitchen where for WeWork the alternative is to work from home...
Prior to WeWork, many companies were (are) in the business of renting commercial real estate. CloudKitchen's bet is creating a huge valuation proposition by making securing a kitchen (as a restauranteur) as easy as provisioning resources on AWS. In a sense, there is some logic there, as restaurants in major cities come and go. There's some degree of food being subject to a fad boom/bust cycle. And as a customer, having access to a constantly rotating set of restaurants, as opposed to a much more static set of brick-and-mortar restaurants in your neighborhood -- maybe you're more likely to engage more with the whatever food delivery app CloudKitchen might eventually make, for it's continuing novelty in dining options.
