It is common place in much of the world (think China). It's US research that's been held back. But I do agree, it is sad.

It doesn't matter if I leave a DNA sample, they can just make one.

Were talking about hundreds of millions of years, what makes you think our current civilization will be stable on those time scales? Large scale disasters such as nuclear war or asteroid strikes that may be unlikely in the short term become very likely given enough time. Any kind of disaster or civilization collapse could lead to groups of humans becoming reproductively isolated, leading to speciation events. The idea that we will still be the same species in a hundred million years time seems pretty unlikely to me. Not impossible, but unlikely.

News flash buddy, all of your genes are monkey genes. Yes, I know you are joking.

Because the asteroids in our solar system are made of the same "star-stuff" that Earth is made from. In other words, the elements in our asteroids were made in the same star or stars as the elements in the Earth. So it's unlikely we'd find any elements in an asteroid that we couldn't find here on Earth. That's why.
