alt Hacker News> Unfortunately, this solves the wrong problem. Spending money usually involves getting a good or service in return, which inherently requires "trust" (as does any human interaction). Your fancy blockchain is not going to help you if you order something with Bitcoin and no package arrives.
That problem already has solutions. The problems cryptocurrency is supposed to solve are, I want to buy subversive literature from someone I already trust not to rip me off, or for an amount I'm not worried about losing, without anyone requiring me to give them a government ID. Or I want to sell it to people without requiring them to give anyone an ID. I want to donate money to Wikileaks. I want to commission art or software from someone in South America who doesn't have access to US banks. I have the same name as someone on a list and I want a way to move money without the government ruining my life. I live in an oppressive country and I want to finance the rebellion, or buy contraception or some other thing which is banned by the baddies when it ought not to be.
It's for doing the things where the existing system fails you, not the things where it works. But it can do those things too. Cash works the same way. You're not worried about a restaurant stealing your money because by the time you pay them you've already eaten. You're not worried about Newegg sending you a brick with "lol" written on it instead of a GPU because they're a well-known company and if they did that it would cost them more in damage to their reputation than they'd gain from the theft and people would sue them independent of payment method.
You don't always need your trust in other people to come from the payment system when it can come from a dozen other things instead.

Only as long as its use for the former doesn't outweigh its use for the latter. Trying to resist a government by using a digital currency is putting the cart before the horse. The dollar is an abstraction and an accounting convenience over the genuine temporal powers of the consensus that issues it.
The blockchain and every transaction being public effectively disproves your entire supposed usecase.

Subversive literature printed on blotter paper.
Outside of buying sex and drugs the only uses for cryptocoins are, and always has been, ransoms, scams and gambling.
That (freedom of payments) may have been the idea. But there are two problems with it:
1. Payments which you can't make today inside a legal system are two types. And if you enable system you automatically enable both types. For libertarians that is a clear 100% positive. For regular centrist citizens, not so much. At minimum it's a topic for debate.
2. BTC and a few other tokens actually make this problem worse. Since blockchain is public, you can always trace "bad" or real bad payment to the source wallet. That i one issue, and another is that since BTCs are non-fungible, the tokens used in such payments are forever tainted. Even in the current anarchic and almost unregulated environment some exchanges are blacklisting some of the tokens, to limit own exposure.
I’m all for bitcoin but your examples are essentially I want to do all these generally illegal things that I cannot within the current legal framework.
Fairly niche things for which the market size nowhere near bears the investment in the technology?

The solution to that problem is "the court orders the bank to send the funds back to my account", including all the way up to clawing back any funds the scammer spent. This is possible when the government controls the currency. It is not possible with crypto.
The only remaining purpose of crypto is funding crime. Some crime you might approve of (buying subversive literature), but that's dwarfed 100000:1 by ransomware, scams, and much more nefarious activity (drugs, sex trafficking, etc.)
