Yep. I think the biggest problem is the assumption that universal basic income would replace any existing welfare programs. In reality, it seems that this is not going to happen, because one size doesn't fit all, and existing welfare programs cover vastly differing cases at vastly differing cost levels (unemployment, disability, old age, serious and not-so-serious illnesses). Over here (Finland), the current government is planning a trial for UBI. It looks like pretty much none of the existing benefits can be cut because they are "fundamental human rights" or similar.
