I like the concept of basic income, but I'm deeply suspicious of SBI.

I agree with @buggedout in that to me it seems to me that "...SBI is basically just a sophisticated circle jerk and skimming operation.", or at least has elements of those.

I won't be participating any time soon, and I'd also like to know if I can remove the SBI unit I got mysteriously and how.

As far as general basic income, I really don't think it needs to be universal. I also don't think any money needs to be printed. The millionaires and billionaires don't need basic income, and might even be able to fund it with their largesse.

It boils down to eat the rich, pun intended.
