It's a strawman because one doesn't have to want people to sit at home all day in order to advocate UBI. An advocate might disagree (rightly or wrongly) that UBI will necessarily lead to people sitting at home all day. An advocate might agree that some people sitting at home all day is a possible undesirable outcome of UBI, but might be willing to tolerate that risk in order to achieve some other outcome that they consider more important. that doesn't mean they want that outcome; just that they are willing to tolerate it if it happens, as long as the expected benefits are also possible. An advocate might even agree that some people sitting at home all day is a necessary and undesirable consequence, but be willing to tolerate it, in order to achieve another desirable outcome. All of these positions are logically possible for a rational person to hold, so long as they don't know them to be wrong. None of them require that person to desire people to sit at home all day. Therefore we cannot conclude from UBI advocacy that the advocate desires people to sit at home all day, which means that claiming they must is a strawman.
