I do see the reasoning in all the topics mentioned above; still the days not everybody has access to cryptocurrency's. So the real intrinsic value will come around when everybody has access to the set of coins and definitely set aside at a bare minimum of the banks. Would you happen to guess how much time will it take for this coins to be made available to the public in such a way that we all give the same value to the items we want to exchange? At that point I believe again it will be the moment in which we realize that we have been dumped for over almost 100 years. Think, who will trust something called Dogecoin these days?
It's not necessary for all the human on earth to be participating to see the effects of the different money in existence today. Some bushmen in the jungle might not use our money but their lifestyle are threaten by the billions of people all chasing fiat currency which is only this tool use for some people to have dominion over some other people and dumped us for so long as you mentioned.
