> the payment mechanism being reversible, it's something else (the storage) that gives

I'm not sure we agree on this being fundamental. At least you can define it as a categorical difference (sure) but not really a practical difference.

I think the articles points were twofold: 1) Property rights, or more generally the legal & regulatory systems, trump any rules imposed or agreed in your system of payments 2) Most payments systems feature reversal processes for necessary reasons (but if they don't, see (1) as fallback position)

Both of these seem important to understand if you want to understand how a payment system works or could work in the future, and also to understand your exposure/risk in using them.

People mostly understand the trade offs and limitations of cash; mostly probably don't understand them well for lots of payment systems.

I don't think the first point is accurate. You have to study the entire system, which is made up of two parts:

1. Storage

2. Payment rail

If your storage is solid (e.g. keys in brain wallet, account in crooked bank, money in shoebox) and the payment rail is solid (e.g. gold, cryptocurrency, cash), you're good. (To clarify, "solid" here means "beyond the legal-regulatory system", which means the rules aren't trumped.) Otherwise, you aren't.

I say that Bitcoin has "finality," because it does the job of payment rail with 100% irreversibility.

Grant that Bitcoin is a mediocre storage (1). But the payment rail (2) truly is irreversible. The combined system of two disjoint parts, built out of bitcoin-as-storage and bitcoin-as-payment-rail, is not.

> "beyond the legal-regulatory system",

I think it is a mistake to believe this is a thing. You can be allowed to operate in gray areas for a bunch of reasons, or you can be small enough not to be too bothered about (e.g. shutting you down not deemed worth the effort); but this is a choice of those same systems, not in your control really.

Although to be fair, I guess this stuff really varies by jurisdiction. Otoh, where the gray areas get bigger, your chances of having that go against you are bigger also.

It's certainly a thing for the payment rail - Bitcoin qua payment rail is entirely irreversible. So as a category in the real world, it is trivially a thing.

Whether such storage exists is a much better question. I think it depends on what you want to do with it. For example, if the Bitfinex guys were ideologically motivated, they could've spent all the money on, I don't know, political ads or whatever. More generally, I think you can certainly come up with storage that is outside the reach of a given threat actor in pursuit of a given goal.

I'm not saying bitcoin isn't a thing in the world; I was saying that I don't think that makes it "beyond the legal-regulatory system", or that that is really even a helpful/useful concept. I mean we can talk about various shadow economies, but they are just that - and not really in scope for OP article.
