There are presumably lots of people and we’re stuck in a light cone with finite mass and energy that needs to be enough for everyone. You can spread out to reach more stuff but there’s a big empty gap after you run out of solar system and need to jump to the next star and a much bigger, emptier gap when you run out of galaxy and need to jump into the next one. And you can think up weird things like accelerating a solar system you’re in to 0.999x the speed of light to do relativistic sightseeing that you probably aren’t ever going to accomplish even with future supertech.
I don’t get how any of these things are obviously nonabundant in an ASI world.
