True, but there remains the question of how people will vote when UBI is on the line. People aren't perfectly rational and it's entirely possible they'll vote for more payments regardless of what other changes that brings, including loss of accountability.
It's hard to imagine people won't bore to get themselves more free shit. If you look at is history and hell Ubi itself, it seems there is no limit to how much p people 'deserve' to take from others.
