Wishful thinking is (necessarily) a thing people do, not a properties of ideas themselves. But I take it what you mean is that when you wrote, in response to Gunnar's comment, "That line of reasoning falls somewhere between the worst elements of Reaganomics and Keynesian economics. It's wishful thinking about something somebody already supports." you meant not that Gunnar in particular was engaging in wishful thinking, but that ... some unspecified other people advocating UBI for the sake of economic stimulus are engaging in wishful thinking.
Fair enough. It might have been worth making it clearer, but of course hindsight is always 20/20.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
