I think it sounds crazy too but I would love to be proven wrong. :) Do you have a background in macroeconomics?
If you're interested in going deep on this stuff, I highly recommend this MOOC:

He doesn't talk about basic income, but this class really helped me understand the nature of money and economic policy.
If you're curious about more about the economics of a deficit-funded basic income, I'm working on a paper about that. Here's the abstract:

Feel free to email me if you're interested in reading the full paper. It's over 50 pages long, but it's not very mathy and should (hopefully) be accessible to non-economists.
