There's a cousin post where I explain how crypto is becoming more useful. As for traditional finance becoming worse...
Suppose somebody approached you in the grocery store and offered to buy your shoes. I assume you have a price, right? I'd walk home from the grocery store shoeless for $100.
Why do we participate in a system which empowers this guy? What about the abstraction he's handing out makes us willing to exchange it for something with less abstract value (there's broken glass on the way home, I'd be taking a risk)? The shallow response is that we can later exchange the abstraction for, for instance, a nicer pair of shoes. But that'll work with anything, so far as somebody else is likely to accept the trade down the line. We could use pebbles or bottlecaps or dogecoin or whatever.
But why USD in particular? What is it about the US government's (or if you prefer, the banks') behavior that entitles them to issue the tokens that we use for bullying people into giving up their shoes (or you know, whatever other economic activity we chose to engage in).
Do you dispute that trust in the government and the banks is steadily declining?
They're fundamentally harder to improve than to erode. It's why nature came up with reproduction: eventually the parasites take over and you have to start fresh. It's why there are very few companies around today that were also around 100 years ago. Entropy wins, it's just what happens to centralized systems over time.
Or to put it less abstractly: We've got banks collapsing and politicians playing chicken over the debt ceiling. Does that not threaten the idea that we can walk home with that $100 and buy a nicer pair of shoes with it? Wouldn't we be better off with a system that was less susceptible to the kind of cancer that ours has?
