On the contrary, massive stellar objects post-AGI will be less useful to you than a house is today, as far as your selfish personal preferences are concerned. Consider the difference in your quality of life living in a nice house vs. skimping and saving 50% and living in a cheap apartment so you can save money. Next, consider the difference in your quality of life owning your own planet (replete with superintelligent servants) vs. owning merely half a planet. What can you do with a whole planet that you can’t do with half a planet? Not that much.
It matters if it means I can live twice as long, because I can purchase more negentropy with which to maintain whatever lifestyle I have.
Good point. If your utility is linear or close to linear in lifespan even at very large scales, and lifespan is based on how much money you have rather than e.g. a right guaranteed by the government, then a planetworth could be almost twice as valuable as half a planetworth.

(My selfish utility is not close to linear in lifespan at very large scales, I think.)
