> Visa does[n't] need to hold the balance of my account.
Yes they do?
> Visa does[n't] need to or makes available all of my equity worth of assets for me to transfer.
This is a horrifying bug, right? A thing that no person would ever want, and it's so rare that visa would make you talk to a person and raise your limit first, or they'd get more people involved to make sure you're not being coerced because it's such an abnormal thing to do. Lawyers in some cases, just because you're being so silly. But if you REALLY wanted to make a $1b debit card transaction, you probably totally could, just call the visa billionaire line.
> Visa does not custody my assets.
But a regular bank can, and visa will send to and from there with a debit card.
"All Property, indeed, except the Savage's temporary Cabin, his Bow, his Matchcoat, and other little Acquisitions, absolutely necessary for his Subsistence, seems to me to be the Creature of public Convention. Hence the Public has the Right of Regulating Descents, and all other Conveyances of Property, and even of limiting the Quantity and the Uses of it. All the Property that is necessary to a Man, for the Conservation of the Individual and the Propagation of the Species, is his natural Right, which none can justly deprive him of: But all Property superfluous to such purposes is the Property of the Publick, who, by their Laws, have created it, and who may therefore by other Laws dispose of it, whenever the Welfare of the Publick shall demand such Disposition. He that does not like civil Society on these Terms, let him retire and live among Savages. He can have no right to the benefits of Society, who will not pay his Club towards the Support of it."
The problem is that if the state were to provide secure public-private key cryptographic identity, there would be absolutely no need for PoW or PoS. Eventually we'll figure that out, and all of this work will haven been useless.
Miners probably have a bit of a sunk cost fallacy, since there's a fixed cost associated with acquiring the hardware. Plus, if they're still bullish on bitcoin, the short term loss is probably worth it in their eyes.
Do most people have more than one theater that they visit frequently? I'd personally be fine with a subscription to just one chain, since almost all chains have almost all of the content.
If I can convince a user to click that, and then login, I can steal their username, password or anything else. Basically anything they do in that window after clicking that link can be compromised.
