(I'm interpreting your comment as "portfolio of planets")

But the corporations would want to spread to all of them. Just like big cities all over the globe look the same, you can buy the same stuff. Trade is good, and I love corporations (never understood why anyone on the left would be against the concept - it's ideally suited to create a "container" for cooperating individuals), but even on our own main planet we can see that we have strong forces of equalization and winner takes all.

You would have to somewhat isolate the places if you want diversity. Same thing that helps with biological diversity. Otherwise it will all just be near-copies of sameness.

In that sense, it would just be like distributed storage of the same content. It helps when one place gets wiped out by accident, but it does not provide true robustness against the "unknown unknowns" (to quote Rumsfeld) that the universe occasionally throws at us.

Space is very good at that. Easy to end up in places that are not practical to reach. Over time things change.
