I have found that the tech and language barrier are simply too much to handle for mine, more than ideological principles or lack of understanding.
Even the ones who are my age or younger just can't handle the complication of getting BTC from an exchange, let alone P2P. Self-custody? Even less.
So, from start, actually operating with BTC is totally out of the question. Lightning network? Get out of here.
Which, of course, makes using BTC as a long term store of wealth to eventually maybe even borrow fiat against, just completely unimaginable.
Yeah, there’s a tech barrier for sure, but also a severe lack of understanding in my experience. This varies from person to person, of course.
Most people just can't make the leap from money to don't trust. Virtually everyone alive today (i.e. , all those in the US born post 1925) has no experience with bearer instrument money. Many are like my wife, "I trust Fidelity to hold my money (bitcoin) more than I trust me to not lose it."
Fortunately, for those that trust Fidelity, Fidelity Crypto has a very nice product that is remarkably similar to an ETF whereby you purchase bitcoin (or actually engage them to purchase bitcoin on your behalf), they take all responsibility for securing it in a set of secure wallets and allocate to your account the fiat exchange rate of the coins you have purchased.
It's not ideal but for those that cannot conceive of money without banks/centralized authorities, it's a start.
