Beyond that, your initial argument was something a bit different. You simply quoted some mathematical symbols and suggested we look at them. But the braces you drew are just delineation. They don't represent anything physical.
I was just arguing that the empty set is not nothing.
Your current argument, as I see it, is akin to telling me that I have a stamp collection, but that my collection has no stamps and never did. Actually, I don't have a stamp collection and I don't want one.
It's that a stamp collection that contains no stamps isn't a stamp collection at all.
