The reason this critique is so prevalent on HN is because a lot of us just watched the last 10 years of the internet go from "that thing that is going to democratize technology and knowledge" to "a centralized management system for privacy invasion." The reason for this seems to be, loosely stated: "no one wants to run their own mail server." Because no one wants to put the effort in to dealing with running an email service, we allow Google, Facebook etc. to run them for us. The reason for this is because our economy is based on specialization of labor: it's by design. I can choose to spend my time running a server, but allowing someone to do it for me is orders of magnitude cheaper due to economies of scale, so unless I have a really strong demand it's probably not going to happen.
The blockchain allows for us the same effect as "running our own email servers," and most of us really don't think it's likely that people are going to want to host their own nodes in the blockchain, because, referring back to Conway's law, there are fundamental political aspects to our culture that do not support this architecture.
The way I see it, one of the big assumptions of the technologies in this space is that participants are only acting out of self-interest. Meaning, that there's a strong push towards designing systems where behaviours that are beneficial to the network are also economically rewarding.
Meaning that in theory, cryptoeconomics could be seen as an attempt at finding a solution to the problem you mention.
Think of the incentivization layer built into something like Filecoin vs the voluntaristic approach of Freenet.
Which leads us back to your point:
> Because no one wants to put the effort in to dealing with running an email service, we allow Google, Facebook etc. to run them for us.
Because until now, you'd have to do it for free.
There are so many projects that promised the world and did not deliver, as well as so many projects that ended up being outright scams, that it's not surprising that when someone says "but what about Blockchain X, Blockchain Y and Blockchain Z projects?", we all roll our eyes and think "I'll believe it when I see it."
It's not as if any blockchain project has provided a long lasting use case beyond speculation, in which case you calling us all idiots would be warranted. After 10 years of flops, the burden to show how interesting these technologies are is on you now.
I don't understand this assessment either. How do you square this with, for example, people who have been able to obtain psychoactive compounds and other medicines that were previously unavailable to them?
And nice try with calling this contraband "medicines". The way to get legitimate medicinal drugs legalized is through careful analysis and discussions, and then you use democracy to make it happen. See California. What you DON'T do is invent some tech that wastes our planet's resources and invent some story about a decentralized future to fool regulators and then enable all kinds of illegal transactions, from human trafficking to terrorism, just so you can smoke a joint effortlessly.
There are plenty of legal things that are difficult to purchase with conventional reversible electronic payments. Off the top of my head:
Gambling deposits (yes, these are legal in most of the world but plagued by chargebacks from losing punters)
porn/sex toys (legal, but people don't want it showing up on their CC statements and don't trust these sites with their CC number)
"Suspicious" purchases with too much chargeback risk (eg. someone wants to buy a Macbook online with a US credit card and a Nigerian shipping address)
"Cash-like purchases" like buying a gold bar or some foreign cash online and having it shipped to your house. The margins on these types of purchases are too small to cover the credit card fees and the chargeback risk is too high because it attracts carders.
I could probably go on, but if you don't think irreversible electronic cash has any legitimate applications, you're not thinking hard enough.
Drug prohibition is not the future of humankind.
If blockchain tech can more quickly undermine it, then I don't think it's reasonable to say that it has no role in making the world a better place.
Additionally, if blockchain tech can substantially undermine a policy entrenched with corruption and enforced by violence, I think it's reasonable to surmise that it has other, less controversial use-cases as well.
The current state of development in this field suggests that I'm right - again, see the technologies above; it's not obvious how they're possible without a distributed consensus mechanism.
I also think that the remark "smoke a joint effortlessly" is both a silly ad-hominen and a red herring. I have been effortlessly smoking joints in all sorts of jurisdictions for the past decade; the change in law really didn't do much to enable that any more than it was already trivial.
However, if I were a member of a less privileged class and wanted to retain some anonymity, or if I wanted access to a more esoteric plant or compound and didn't have the social connectivity to obtain it, then I think that I'd find a mechanism to subvert these prohibitions very helpful.
Not everyone has the same opportunities and protections as you. Your implicit suggestion that everyone simply live in California is very insensitive. Technologies that tend to smooth this disparity are reasonable to celebrate.
