I don’t have a straight answer to your question. I’ve noticed the same - people just don’t get it or don’t want to hear it. Even those who do, get attracted to different aspects of Bitcoin, as it has so many.

The visionaries are few, and see how things could be different and better - the best among them see how things MUST be.

Most are conservatives, and work to keep what works working. They will be interested only when they can buy things with bitcoin.

Eventually when you can buy things only with bitcoin, the conservatives will be the majority of bitcoin users.
