If someone can present an actual spreadsheet showing where the money would come from and how to avoid impacting the prices of things that people requiring BI would be purchasing, then I would be extremely interested in it, but I am willing to flat out say that it's impossible to cough up $2.7 trillion yearly (that's 18% of the US's GDP) without moving the needle in a substantial manner.
Out of curiosity, I ran some BI numbers and arrived at a similar figure ($2.9T/yr, 17% of GDP, 81% of the entire federal budget).
I dug into some numbers to try to figure out what kind of tax rate you'd need to make that work. It's... challenging to say the least.
What I did find however was that in terms of income distribution, only 23M households were making <$20K/yr (mean household size was 2). An incredibly rough number, but you could run a Guaranteed Minimum Income program for $20K/yr for about 10x less (1.7% GDP) - you'd get that for free if you switched to single-payer nationalized health care (Canada, Germany, France, UK, Japan costs are 9-11% GDP while the US currently spends just under 18% GDP)[1]
This of course will never happen in the US because it'd make too much sense.
I would expect that BI would (and should) have an impact on the cost of housing.
If the BI is constant across a geographical area that has varying housing costs then people without any other income would choose to live in cheaper areas, those living in currently expensive areas would have to pay more for basic services to allow people providing them to live nearby. I think this would help to deflate the current housing bubbles.
