How would barter system prevent the goods made by robots? As long as robot-employing countries remain, they will still produce cheaper goods. All this means is that if I need a pencil, I will go to my local "trader" to barter things I have for imported, industrially-produced pencils. even with shipping, a pencil factory overseas will still produce much cheaper pencils that artisanal pencil maker. More technologically advanced items would be even worse. If you want people to shun goods made by robots, you should campaign for visible "MADE BY ROBOTS" markings on relevant products, educate people why this is bad, and maybe also tax such produce extra for a good measure. Of course, it may not work very well, may have an opposite effect (see "Made In Germany" story), and will definitely introduce potential for abuse and gaming of the system.
