Self-hosting means that the person who does the administering, has no control over the infrastructure, configuration, etc. There are millions of ways in which something could be configured. The user could have installed a kernel extension that panics every 2 days, for all he knows. This means that the administrator must be sufficiently skilled to be able to handle all anything that might come at him. Which means that he's expensive. This makes it economically hard to compete against hosting, where they administrators can be cheaper due to having more controlled environments. One solution is for administrators to insist on that environment conforms to some sort of standard. But no meaningful standardization currently exist for this context. Making the device/software resilient enough, is also very hard, and suffers the same problems as with human administrators. If you install a device in a network with a faulty router, then what is that device supposed to do? How does it even know the router is the culprit?
