I don't care about any of the use cases you mention because those are made up. The need to transfer value isn't.
There's a new Stripe or Paypal horror story on HN every other week, and the only way to get around them is to trust the next best entity until they break down, or to give up more privacy than a simple purchase should ever require.
All financial contracts on these systems must be fully- or over-collateralized, and if the collateral is used up there’s no margin calls for more, instead the contract is automatically closed. That creates an immense buffer against cascading financial collapse and house-of cards style financial structures that Wall St. likes to build.
The possibility of a GFC or Great Depression (leveraged credit crises/collapse) is arguably the single biggest problem in all of the traditional financial system. Cryptocurrency may solve it.
The kind of unsafe leveraged bundling that caused the great financial crisis was already illegal. In theory, the banks should have suffered the consequences of their poor trades. In practice, both the banks and the government knew that by enforcing those consequences, the entire financial system as we knew it would fall apart. So the banks smartly factored the bailouts into their risk calculations when entering into those trades.
Crypto enables systems that cannot be as easily bailed out. It changes the game theory so that failure is no longer a "get bailout and still win" condition for speculative lenders. So in a way, crypto absolutely does create "ways to make breaches of trust cost more."
With little or no debt, economic growth will no doubt be slower in the short/medium term. But an equity-only system with slower growth might be comparable in the long-run, due to continuous growth with no principle drawdowns and setbacks from periodic financial collapses.
I don’t know of any research attempting such comparisons, everyone assumes debt is inevitable and doesn’t bother thinking about this.
That said, if somehow you had a similar hypothetical economy but with little or no debt, the equity side might be larger.
There are many ways to prevent Wall Street or other organizations from becoming overleveraged.
My point is, crypto may represent a permanent and deterministic solution this problem, implemented at the protocol/infrastructure level, and which is difficult or impossible to corrupt via lobbying and political capture.
Receiving payments from abroad is far faster and cheaper than bank transfers, and I can do it ignoring restrictions by various governments.
I can finance anti-Putin initiatives without risk of getting caught and prosecuted.
Bitcoins is a godsend and even if it didn't have any other uses, these would be enough to make it valuable.
Idk if I’d be so confident about this point.
The white paper was written 13 years ago. What actual problems does it legally solve?
Store of value? Not so successful. Inflation hedge? Nope. Micropayments? Nobody wants them - any traditional financial company could implement it instantly. If people wanted it.
So we are left with the few things that cryptocurrency has actually been good at: tax avoidance, illicit transactions and ransomware.
Cryptocurrency has been a scourge and has no redeeming quantities.
ETH mining did pay for a computer I bought a few times over though so I guess thanks for that.
