I can tell you just grabbed the first result of a Google search "why basic income works" because you linked an article with a pay wall that doesn't actually allow you to read it, leading me to believe you didn't read it either. So thanks.
However, just the title and first paragraph I was able to skim highlight the point I'm making: it doesn't matter if a system works if not enough people are willing to adopt it. Which is what the concept of the overton window is built on.
