OTOH you can see it as an investment to make new content. The question however is what the cost versus benefit is. I don't know the exact costs but business wise it likely is a large risk. In that light Dave is pretty clever with his test equipment review, mailbag and dumpster-diving repair videos. Costs him next to nothing in materials to make.
That is a valid point, although it seems like a bit of a risky investment. There are some fascinating videos she has done, I liked the series in the Apollo DSKY, and the various esoteric display technologies are fascinating. Those sorts of topics are relatively low cost (and thus low risk) and fairly high reward in that they are interesting content.
Either way if I were in her position with regards to housing, I would put the youtube channel on the back burner and look for a job, any job that will pay the bills. There is a massive labor shortage across the USA right now. We need truck drivers, that doesn't need any kind of degree or even a whole lot of training. We need people in the trades, that usually needs an apprenticeship but you get paid. On the engineering side we need software engineers, my employer has been hiring like crazy and can't find enough senior SDEs, they can even be approved to work fully remotely if desired. Her living situation has already been discussed to death but sometimes the simple reality is that a person has to find somewhere different to live, something she has apparently been totally unwilling to do. There are numerous solutions to the problem and yet from my admittedly limited view of the saga, it appears she is trying the same thing over and over expecting different results.
