People usually care about things only when they are affected personally or when someone knocks on their door.
All movement in world today is to abolish all form of privacy and make everything into ''Big Brother'' reality when you are constantly recorded and tracked 24/7.
I don't think that majority of people wants this, even if they are bribed with free stuff along the way.
The other issue is people do not understand how or why many things work. So when someone comes along and offers them "privacy" they really do not know what they are getting and how it really works.
Want a really secure encrypted device that can't be tracked because you are a criminal:

How about just a phone that is secure that does not spy on you:

BTC privacy. If you are doing a P2P trade F2F how are you sending your
BTC to the other person. Electrum on a phone or laptop? Do you know what back end server you are connecting to and what it records? Unless you are running you own node you don't. Are you using Wi-Fi in a coffee shop? Are you 100% sure that there is no MITM attack going on?
How much do you know about the person you are trading with? How good is their OPSec?
I don't want to be that guy who says it can't be done, but I really think that it's a lot more complicated then a lot of people think.
