What are you quoting with the quotation marks? I agree with you on that a BI that ends in 1 year isn't a good test. However, from the article their goal with the sort-term pilot is "to prepare for the longer-term study by working on our methods--how to pay people, how to collect data, how to randomly choose a sample, etc". So...who cares if the short-term pilot isn't a good study on BI? That's not their goal. I disag…
The point of BI is that you wouldn't have to worry about supporting yourself for the bare necessities. If it's only 10 years long you still have to consider your career prospects after you lose BI. If you tell an employer "I've been out of a job for 10 years because I got free money and didn't need to work" they aren't exactly going to jump at the chance to hire you. Plus your skills will be out of date.
I know very few people who only work in order to secure for themselves the bare necessities of life. I suspect, even in an infinite BI world, many people would work in order to be able to have more than the bare necessities.
However, anecdotal evidence such as "people I personally know" is terrible evidence for making drastic changes to our social welfare programs. Which is why we need small scale studies and pilot programs in order to begin to assess the data of how people behave when they receive BI.

No, but if you really didn't want to work, you could easily take 6 years off and then spend 2 years on education, and another 2 years getting back into the job market. It would be really good to have this kind of data.
