it does matter. people curiosity will always push them to look for satoshi and know him. it also matters because most of bitcoin holders are afraid from the first mined coins to be spent which can cause a big inflation
If people really worry about that, then they should get really worried when the price goes up to much higher price levels than now, and Mark Karpeles start dumping "his" 300-500K stash. This is a much bigger threat and no one seem to care about it. Satoshi isn't revealing himself for a reason and he haven't touched his coins for a reason.
