Well, Basic Job is sort of by definition work that doesn't need doing. There's a fundamental conceptual problem with it:
Imagine I, for whatever reason, accept a Basic Job from the government. The job is, by design, bad. I'd rather not do it. So my dream scenario is that I officially hold a Basic Job and draw its meager salary, but instead of doing whatever work it supposedly entails I sit at home and watch TV.
This scenario isn't just an improvement in my life -- it's also an improvement for everyone handling me! The work doesn't need to get done; it's only there as a penalty for me, to encourage me not to draw the Basic Salary if I don't really, truly need it. So when I save myself some effort by not showing up for work, I also save my handlers effort that might have gone into overseeing me. Just as it's easier for me to stay home, it's easier for them to pretend I didn't than to track whether or not I did anything. So overseeing Basic Job is conceptually pretty difficult.
I don't claim that this is more or less difficult to deal with than the problems of any other welfare system, but it is an obvious and fundamental flaw in the concept, and might help explain why it's hard for Basic Job to get traction. On a shallower level, the concept of "pay someone to dig a hole today and fill it in tomorrow" (a.k.a. The Basic Job Concept), has been the go-to example for exactly what we don't want government to do for a long, long time. That can also make it difficult to get traction.

This is a fundamental misunderstanding. BJ is work that is not worth doing at current market prices. I.e., picking up garbage in the park might be worth $4/hour, but minimum wage is $7.25/hour. If we spend $7.25 more and get $4.00 worth of value out of it, we lost $3.25.
If we are already spending $7.25 on welfare/BI and getting nothing in return, we are losing $7.25. If we demand that recipients work for their money we lose only $3.25. As long as the BJ workers are not destructive, we lose less money than we otherwise would with welfare or a BI.
Also, the jobs need not be "dig a hole and fill it in" - they can also be "walk around town and find potholes to fill tomorrow" or "there is garbage on the streets, go clean it up". It's not as if we have a shortage of things that would be beneficial if we did them. They just might not be worth doing at current prices.
This raises a pretty interesting question. Suppose I apply for a Basic Job at your institution, where all the work is sort of worthwhile, but not worthwhile enough to happen unsubsidized. What job do you assign to me? How do you choose it? I assume you're not choosing the "most worthwhile" of the jobs, because how would you know?
If the work is digging holes one day and undigging them the next, overhead here is low. If there's some other system behind what the jobs are and how they get filled, potential for corruption seems extremely high. Say I'm a Denny's and I'd rather not pay so much for my kitchen staff. Can I list all the positions with Basic Job and kick back to the administrator when he sends me someone?
Germany has no minimum wage and extremely low unemployment. What would their Basic Jobs be?
The basic income goes towards making sure the worthless jobs don't get done anyway. It's more like eliminating the minimum wage and then using the existing welfare state mechanisms to float everyone's consumption up to a floor of $20k / year as long as they have a job.

Not at all. There are things that provide economic value that is hard to capture. Determining what those things are and how to value them is going to be messy, though.
