Donation of what? It only makes sense if the purpose of Bitcoin is to go up in fiat denominated terms, but that’s not a currency it’s a Ponzi scheme.
I think you're either reading too much into it, or are interpreting "donation" too literally. He's just pointing out the very simple fact that if there is less of a scarce resource, then the value of what remains goes up, all things being equal. He's not advocating that people burn their bitcoins intentionally to make everyone rich or whatever. The whole thing is just a subtle joke, and it seems like you missed it.
The guidelines are more than merely rules. They’re the glue that holds us together and prevents us from tearing each other apart in political flamewar.

Perhaps a stroll by this would have been useful for a core dev with $3.2 million in a wallet stored in a profoundly stupid way on a server.
