UBI is a solution to the problem of structural unemployment when due to advances in automation we don't have enough reasonable jobs for people who are capable of working, when we don't really want everyone to work as much. If we need everyone who can work to actually work, if we want to force people to work with a threat that if they don't contribute to society then they'll be (for example) homeless - well, then we don't (yet) need UBI and should not implement UBI until(if) we get the problem which UBI would fix.
