Its quite an interesting question you asked here mate, I see reasons with what you asked, there are some underdeveloped countries of which in a very long time, crypto will still appear strange to them.
Here's my opinion, I think since the banks can make use of ussd codes to run transactions even when you are offline, there should be room for such things in crypto. To make it easier and accessible by those in rural areas.
My second opinion is that since the internet is a paramount part of the crypto community, every ecosystem should be able to send some delegates who are capable of teaching to, put through some people with still primitive mindset, and enlighten them on how to operate and interact with crypto, so as to make it generally acceptable.
