Now that we have the high carbon content stainless knives there is no problem that I see. If you can cut.
I think the idea is that cutting with a knife slices right through the cells of the plant, whereas tearing will leave more of them intact, thus resulting in fewer ruptured cells and less loss of essential oils (which evaporate redily), less exposure of cell contents to atmospheric oxygen, etc.
I have my doubts concerning that theory. I like yours (reactive vs. stainless knives) better.
Regarding slicing basil leaves individually vs. stacking them, it sounds like a wonderful way to waste a lot of time without any real benefit to the final dish. In fact, since it's bound to take about 10 times longer to cut up the basil that way, it is actually detrimental, since it means those first leaves sit around, losing their essential oils the whole time, for a lot longer.
