It's somewhat of a stretch to compare capital income and UBI. The people receiving capital income today are reaping the benefits of their prior income that they had paid taxes for, and chosen to save instead of spend. This is qualitatively different from someone getting a no-strings-attached payment from the government. I'm all in favor of UBI, but this doesn't sound like a valid argument.
