If I get hit by a bus, there is a list of people/companies that can take over the business and continue to develop/maintain it. And since it is a viable business, it will make sense for someone to take over.

Please note that getting hit by a bus should be considered in terms of probabilities: while possible, compare it to the near-certainty of "something" happening to a VC-funded business within 3 years, where none of the "somethings" are good for customers.
