If by some weird magic I had today all the BTCs forever locked in Nakamoto's wallet, currently around $23 billion, I would give them all away just to be able to live in 2140, the year the last BTC will be mined. So I guess BTC is actually a currency after all, haha.

presumably, a static supply in a growing(?) economy means it continues its deflationary dynamics.

And the miners would all shut down because no one's transacting with it
