First, the picture you showed does not look rural to me,
It is a village that is close to settlements and not so far from the city so that everyone who lives there is always easier to do activities and access to the city.
Which country it is?
INDONESIA
Actually, that a person is seen wearing a Bitcoin t-shirt doesn't mean he or she knows about Bitcoin, because at times such people may be wearing the t-shirt for years but never noticed "Bitcoin" was written on it. Don't be surprise. Because Bitcoin goes beyond mere write-up on a t-shirt,
It could be so, because what you say is still possible to be true. But logically, he who wears a shirt that says Bitcoin will also not make a screen printing on his shirt if he doesn't know what Bitcoin is because here there are no shops selling clothes that say Bitcoin.
Unless he ordered it through an online shop on his smartphone.
May I ask how did you find out about Bitcoin?
I know about Bitcoin through people who are not near me, but I can still contact them when I have a question about Bitcoin. And I also don't know if they know about this forum because they just invited me to play on some crypto exchanges for trading and they told me to look at Bitcoin more.
How do you know that they don't want to know crypto or are not interested in crypto?
I conclude that because in the past I have offered some people who live near me to give education about crypto for free, but they turned it down and instead said Bitcoin was bullshit. So I decided to distance myself from them and never told them about crypto again until now.
