Crypto is definitely the next generation currency world because it relies on technology which is what the near future would mostly consist of... lots of integration with highly advanced technology. Whereas for the government, I'm sure they will form a much stronger opposition to the crypto world when they're about to realize how real this is going to be, but honestly I can envision a system with full decentralization and no need for government.
How would society function without a government, in theory?
Is it full capitalism where people with money can afford to pay for things such as health care, roads around their area etc?
with no taxes at all, everyone 'pools' together money in their areas to get what they need(a bit like gated communities?)
How would countries work together politically to reach goals? or is crypto the road to 'NWO'?
