Is there any hindrance to this idea?
Ideas like this might sound good to some while not the same to others. Certainly, I think the government might be the number one hindrance to such ideas, as they would keep feeding the minds of every generation with corrupted banks and financial institutions, making every generation believe that only banks and financial institutions are the places worth leaving our money.
In addition, when every generation keeps using fiat currency, it would be very easy for financial institutions to print excessive money for their own selfish interests. So I think those in power might be a significant setback we might face in many countries.
This sounds like a conspiracy theory. Everything is much simpler and this is what it looks like depending on the country.
Any school has a training program drawn up and certified by a higher authority (in fact, government bodies). Therefore, changing the school curriculum is possible only with their consent. Given the non-acceptance and denial of bitcoin by government, adding (formal) training on the basics of using bitcoin is unlikely. I believe this will require going through 9 circles of bureaucratic hell.
On the other hand, why do you need school to learn the basics about bitcoin? No one and nothing can interfere with your self-education.
