Did someone say otherwise?
Crypto is an attempt to fulfill a broad yearning for financial freedom. The problem is, as it currently exists --- it just doesn't deliver.
Crypto doesn't displace trust, it misplaces it.
Instead of trusting government and regulated banks, you end up trusting the unregulated gatekeepers to the block chain --- the exchanges.
Who is making sure these gatekeepers are not self serving scammers and con artists? Why no one really.
In other words, block chain automates the accounting but it does nothing to eliminate *trust* as a central aspect of the monetary system. So the question simply becomes, who are you going to trust?
If government suddenly ceased to exist, the first thing people would do is re-invent it. Because left to their own devices, people are not trustworthy.
