Don't underestimate the power of ideas. Who knows, there might come a time when governments would be led by people who are convinced that money should be made completely independent from the state. It has been proven countless of times that states can't be trusted with the power over money. Money has only been debased, devalued, squandered by governments. I guess time might come when leaders would realize that. At which point, Bitcoin might be the first alternative.
True that we can not underestimate the power of idea but not all government will want to support such ideas especially when it comes money and even if it will happen it's going to be a very long time, the government always want something to control since they are the ones issuing our money because with recognition of the government it does not have value.
Only few countries can take a bold decision when it comes to accepting bitcoin and El Salvador have been fully supported when it comes to bitcoin affairs and they don't have any difficulty in what so ever they are doing even making it a legal tender, the bold step will also encourage other countries to give a try, some countries are finding it hard for them to make it legal talk more of recognition as a legal tender.
I hope to see that time come because a lot have been happening within the finance they have shown that it is the main reason why they are their they don't longer driven by leadership but by the money they will be able to embezzle when they get their.
