They throw that stuff away so SHOULD be free.
I see others have preceded me here, and for good reason: they're right.
That white plastic is some slick stuff, and is great at that application.
Also, some cable liners, such as those that come in Tarmacs and other internally routed frames will work.
If you're going with straight-out cable housing, I recommend a piece of brake housing, perhaps the larger inner space would be better for your application.
I have seen what you showed, and I have seen it (and done it) with the stainless coiled housing that doesn't compress. In fact, I think on some bikes, that was originally there, because the FD had a cable stop built onto the back of it.
