Volunteers all over this great land do all sorts of things, but it's also the case that many services that are needed are subsidized in some way by charitable contributions - it's not a homogeneous landscape.
You're still making assumptions about what it takes to do this work - you don't know, so why make criticisms out of ignorance of the facts?
It very well may be that the artist (or maybe others as well) would have some expenses defrayed by contributions - the point is filling the gap from what he or others may be willing to simply do as you put it "one on one" and what it takes to reach more affected individuals, which you minimized and frankly marginalized in your previous post. No doubt contributors may want information about how the money is spent - whomever is raising the money would certainly be up front about it, no reason to jump to conclusions because you had a bad experience - you can always find a tale about a charity that didn't do what it should have been doing.
His question is about how to raise money as I see it, not about having people pick apart what he's doing in terms of his motives - not really fair or relevant.
