You are making the case that it's currently impractical. That is very different from "as inevitable as [the] CAP theorem".
For instance, if the cost of "basic life necessities" was somehow $5/yr, but incomes (and tax revenues) similar to today (... presumably people are spending an awful lot on luxury goods?), it could certainly be all three of those things.
It may be the case that that is somehow impossible, but that's a case that you need to make in some way other than listing off what the current numbers happen to be.
I expect that you believe that UBI is impossible. I am not interested in continuing to engage with you because you are not interested in engaging intellectually and analyzing why you might be wrong or helping others analyze why they might be wrong, but are focused exclusively on scoring rhetorical points. That's sometimes a fun game to play, but it's not productive and it's not why I come to HN.
