How many people use Bitcoin in a self-sovereign manner, and do not use fiat/trad-fi banking?

How many businesses do this?

Most people are keyboard warriors LARPing about being outside of Fiat. Most people will stay within the system designed for them.

Very few people are preparing to setup shadow markets and private economies. Most of these people understand that Bitcoin, as it exists today, is not the best tool for these type of markets.
