instead, teach them the basic about bitcoin which is a payment method where they can use online or they can do a person to person transaction
You gotta explain to people how Bitcoin is better than banks, because simply being an online payment method for p2p transactions is not enough, companies like PayPal and Venmo and countless others have been offering it for years, and with simpler user experience. Privacy is a perfectly valid point, these days people are paying for VPN and are installing anti-tracking addons, so there's nothing negative about that.
