Satoshi (or one of his friends) owns 5% of all bitcoins that will ever exist.

I wouldn't call it a get rich quick scheme for its founder(s) because I doubt they could have known it would take off the way it did.

But, at this point, I don't know that intent matters. Imagine if Bitcoin really did become a dominant currency... one guy would own 5% of it, a deflationary currency! The "fiat billionaires" don't come anywhere close to that kind of concentration of wealth.

The thing with ideologies (and other kinds of socioeconomical hypotheses) is that they're hyperstitional in nature - you can't prove they're realizable without at the same time deliberately trying to realize them, using people as fodder. (See, communism.) And at least one of the ideologies promulgated in meme-space must have some basis in potential reality (otherwise people wouldn't be at all prone to believing in world-changing ideas). Might be this one, might be not.
