The capability of self-custody is the thing to pay attention to.
Nothing else has this capability to the same extent.
Today we store most of our wealth in assets (market index funds, stocks, real estate, etc.) and some (typically very little, and rarely outside of a bank account) in cash.
Most of this is not actually controlled by you.
With BTC (and cryptocurrency more generally) you have the capability of having your private key in a hardware wallet under your control and retain the capability to transact independently of other institutions.
If you keep some percentage of your wealth here you retain certain advantages that you can't get elsewhere. The closest alternative would be having cash (in cash form), but it's hard to have that much, hard to travel with it (you can memorize your wallet seed words and recreate your wallet on the other side of a border), and cash is vulnerable to government stupidity (see: Russia).
I'm not sympathetic to the Canadian truck protests, but whether or not you care about what they're protesting - it's the capability wielded by the Canadian government over their private finances that's alarming.
All this is to say the focus on middleman and paying with crypto in the general case is kind of missing the forest for the trees.
The capability of a global self-custody capable store of value that can be trivially moved anywhere is a big deal and puts power back in the hands of individuals.
