After UBI is implemented. The minimum needed to live will be equivalent to UBI.
As for the rest of your comment, the fact you refer to government as "govern-cement" shows your lack of ability to have any kind of serious discussion.
UBI is unconditional. That's the entire point of it, to remove the ability of government to dictate terms, and also shrink the size of the state down by removing the need of countless bureaucrats. This is why Milton Friedman himself supported it.
If you hate government so much, what's your solution to the automation of human labor? What do you think is going to happen when millions of paid drivers become unemployable, and millions of other jobs fall to AI? Have you got any answer to offer other than "govern-cement is evil'?
Hell, let's even just look at the here and now. What's your solution to the problem of the working poor? What's your solution to the fact tens of million of people are working, and yet don't earn enough to live above the poverty line?
Well, since section 8 housing basically made all the cheap apartments rent at the section 8 housing level, I don't see how you could claim that the basics will cost anything but the amount given in UBI. It might be different this time, but It has happened in every other controlled environment.
Govern-cement is out to kill or control all the people. So, until that gets changed, I will not get behind any plan that involves the govern-cement. And you think I am just being obstinate? I am just one of those "conspiracy wack-jobs"? And thus I can't have a decent conversation?
I do not hold much kin with Rothbard. But two people who wrote extensively about UBI you might want to read.
