Here's a more accurate way to estimate bitcoin's fees. Go to mempool.space and look at the current estimated Low/Medium/High priority fees. That is based on current pending transactions and most of the time, unless you are in a hurry, "Low" is enough to get a transaction confirmed in the next hour.

And this is the expensive way to transact bitcoin -- on-chain! Nowadays most commerce is moving to the layer-2 Lightning Network, where transactions are instant and typically nearly free via payment channels that are settled on-chain in the future.
Each channel sets their own rates so the cost of transacting this way varies but it usually comes out to a very tiny amount, much less than 0.1%.

This is a fair point, but I would argue that people who are unbanked are not the kind of people who will find it easy to securely manage crypto keys and wallets.
