I agree, that's basically where I drew inspiration, but I wasn't very clear as I intend this to replace all (or most) other taxes such as income, sales and property (maybe not property tax). I think it differs from a UBI in that the amount is variable, being percentage based, and could be justified as a something that is owed to the economic stakeholders hopefully avoiding the perception of being a handout. It would be like your citizenship payed dividends based on the GDP. I think this more closely resembles the "Fair Tax" which is itself a variation and combination of a VAT and UBI.
