I'll try to explain simpler. It's not actual to refer everything to "at this point", "at this time". Of course, it's impossible right now to stop exporting oil and immediately to begin to export a lot of high-tech products. Imagine it like a graph, not as some sticked point. Now, for example, you can't produce a product but when there is a change of conditions to one degree you could do it, when there is another change you could produce another product and that cause others products and so on. And that refinement of crude resources is one step that itself can cause other things. Once there is a bit decrease of selling oil you'll see producing a number of released products, another bit - another number and so forth.
No, it's doesn't sound like a point to what I've explained
It's difficult to comment that because you missing a lot of points.
