I’ve already done the math about how hard it is to chuck a relativistic rock. Assuming solar output, you could arguably maybe do it as a Kardashev I, but it’s more a Kadashev II thing. It gets harder if you find yourself born around a common red dwarf. If Zaphod Beeblebrox is chucking asteroids for lolz, while he waits for Slartibartfast to finish building a new pleasure planet (with space blackjack, and three boobed Martian hookers from Total Recall no doubt), we’re dealing with residents of Mount Olympus, with Zaphod playing the role of Zeus. Come to think of it. That would certainly make the ancient alien conspiracies more entertaining —- and more terrifying.
