A Dyson sphere around a black hole

What if by the time you get to that level of technology, you no longer need that much physical space? I don't even mean in a soft sci-fi "evolutionary progress means becoming energy beings", I mean a hard sci-fi "advanced civilizations just digitize themselves into a virtual reality simulations."

For the same reason we eat free range X, hike about in the untouched mountains, like to drive ourselves, despite intravenous food, urban environments and train being readily available.

Its not about need, but about want. If you can have anything, my bet is that a Dyson sphere makes more sense than Cyberpunk tech and eating protein goop. Although there is space enough on the sphere for people that prefer it, of course, which there no doubt will be.

You won't need physical space but you'd still need energy to run that VR simulation.
