Besides that I am not sure about you comment, I am not sure how you interpreted my comment with the spelling error. I am especially confused because your first paragraph sounds like you are arguing for automation, the second paragraphs sounds like you consider it harmful for unskilled workers. I don't want to outlaw any automation, quite the opposite, I would consider the ultimate goal a world where all work is done by robots and nobody has to work.
Now, in which system can a neighbor earn an extra $20 a week for a morning of work? In which system does my front garden look nicer from the sidewalk? Someone (probably a teen) gets some walking around money, the whole neighborhood gets a nicer sidewalk view, and I don't have to do an optional job that I dislike. Sounds like a winner all around to me, but no way is "pulling weeds" a full-time, live alone and without additional support career.
All of which perpetuates the cash/grey economy (and the off-shoring of garment-making jobs in your example).
The thing about UBI is that it allows employees to turn down bad economic deals without starving. Sure, you can't live in a 2000 ft^2 house, drive a new car, eat and party out all the time, but you probably don't have to take a job with ridiculously bad conditions just so you can buy a can of beans or Ramen.
There are all sorts of things that people will pay a handful of dollars for, but that they won't/can't pay $10/hr for. Mine was just a concrete example of a low skill required task that I don't enjoy and that someone whose basic needs were already covered might be interested in doing, much like I did when I was a kid/teen and wanted to earn some extra money.
I am in favor of automation (for the same reasons you are, I think), and automation does harm unskilled workers.
Between the present day and the future golden age of robotics that we both desire is a period of time in which some fraction of the population, who have specialized skills that are hard to automate, will work for a living, while another fraction (probably larger than the first) of the population will have nothing to offer in return for money. I don't see any way around the first group subsidizing the existence of the second.
Are you saying you'd outlaw self-service gas pumps and checkout stations? Robotic assembly lines and autonomous vehicles?
A large fraction of the population has no distinguishing skills. That segment of the population is going to find itself with ever fewer ways to earn a living.
