I probably don't understand you in full but the idea of private capital is based on the opposite - that there is no dependency on a single person.

This was seen as a major risk of Apple ("what's going to happen if Steve dies, last time they got rid of him it almost went under"), and held its stock back for a considerable time before market accepted that dependence on that 1 person wasn't as big as feared.

This is seen as a major risk of SpaceX now, too. Companies are not people. A company that's worth something - not just makes a profit - shouldn't be dependent on one person, because you can't sell a person due to 13th Amendment, but being worth something means that one can buy and sell.
