There are lots of places where owning gold is difficult/impossible, but anyone can sock some money away into a few satoshis. That's the use-case you're ignoring.

If you don't know anyone from such a place, I can tell you that much of the 2nd world and perhaps all of the 3rd world is dangerously corrupt, and their banking sectors are no different. I have a friend from Venezuela who saved up money for years, depositing money into a Venezuelan bank only to see his entire savings drained overnight with no explanation. How many times does that have to happen before you put money into BTC instead? These people aren't scammers or speculators or blackmailers: they're trying to keep what they earn. Seems crappy to ignore this use-case.
