How far can btc price fall where it's affordable to buy every available Satoshi.

Example price goes to $60k. Surely if it's that cheap most investors can now afford to buy a full coin. And there's way more than 21mill investors on the planet. Scarcity in that scenario should skyrocket the price?
Even the recent $79k drop, surprises me at that affordable price to buy a whole coin, the market didn't clean up driving up demand and price.
