To give more details

Uber is not a saas, it sell the ability to match drivers with people. You can code an uber-like software easily and you will find that it leads to nowhere: no network => no driver + no consumer = you have nothing

Another kind of business is online bank: are they just software ? Yes, obviously. Are they software-as-a-service ? Obviously not: they sell regulation, integration with financial stuff, government approbation and what-not

Just because a company is used via software-only does not mean that it has a saas

On the other hand, you have companies like tesla, which are far more "software-as-a-service" than online banks

What a funny world
