No one even came close to suggesting that a redistributional tax scheme is free.

But interestingly: basic income provides more benefits with as income inequality goes up. That is, if everyone in society already has the same level of income, there would be no way to finance basic income through income tax. You would collect the same amount of tax from every person and then give it right back to them. However, in your hypothetical distribution, that one person at the top is singlehandedly providing the basic income of 2% of the population. And we are using your proposed very fair taxation scheme of flat tax. And in reality, income distributions are far more skewed than your hypothetical distribution.

Great-grandparent comment implied the only cost you need to consider is for unemployed people i.e. that it's free for those who are employed . That's wrong.

That's not at all what the great-grandparent comment said. It was talking about the aggregate cost of the entire system. And the great-great-grandparent was wondering "just where is the money going to come from?" but fundamentally it's not a problem. As long as the total basic income of a country is less than the total income of a country, the latter can be redistributed into the former.

By this argument, if the basic income == the total income of a country, there is still no aggregate cost. Maybe, but I'd argue that such a system would come with huge costs due to the massive increase in taxation.
