Agreed on all points. That's what I meant when I rephrased my conclusion as saying that nature isn't creating it in sufficient quantities (and in sufficient frequency) for us to see them. It may be happening, but if it isn't constantly being replenished, the minute quantities that are being created aren't enough to be detected from here.
We can create it but we can't store it for very long--perhaps the universe is the same way.
Well, anti-hydrogen is difficult to store because it is electrically neutral. It's as difficult to store as hydrogen, actually. But nature has found a way to store hydrogen and it works the same way for anti-hydrogen: gravity.
In other words: we haven't found any anti-matter star, brown dwarf, or gas giant.
