| > The blockchain, on the other hand, was invented to keep track of who owns that. That's its only purpose. Well.. its purpose is to enable transactions between people, and not keep track of legal ownership of things. In fact, these networks usually don't make any claim about who legally owns anything: only about who controls something (i.e. who owns it within the system, not who owns it in the legal sense). Does physical cash keep track of who actually owns it (and not just "who posesses it")? No. Does that make it useless or fatally flawed for the purpose of "value exchange"? Not really. If you receive a 10 USD bill from someone as payment, you have to assume that they own that bill (and didn't just steal from anyone else). The bill itself doesn't enforce property law. Furthermore, if you have lax security and a pickpocket takes your wallet (with 500 USD inside), you also have little recourse or method to enforce your ownership of the stolen cash. In fact, you probably even have less recourse than with things on blockchains: there's no way of tracking where cash goes, after someone steals it from you. Is the fact that "cash" doesn't encode/enforce your property rights over it a problem that prevents "cash" from being effectively used a medium of value exchange between people? As far as I can tell, no. Just like with "blockchains", if someone steals your cash, or anything else, you need to go to a court to get things fixed. I understand your argument and accept that such properties of the system could be seen as "design flaws" (though... how could you even fix such design flaws? "law" is not a formal system). On the other hand, if such properties were "fatal design flaws" (for the purpose of a system of value exchange between economical agents), then plain vanilla cash is just as flawed, if not more (since it does not encode or enforce your property rights, and it's even less traceable than blockchain "assets"). |
Now, back to blockchains. Blockchains are very inefficient and expensive to run. This is so, because they have to do a whole lot of extra work in order to avoid relying on a central authority that ultimately has the final say on who owns what. If blockchain users have to go to court to have property rights enforced, that means that the courts do have the final say on who owns what, and so the entire purpose of the blockchain, which was to avoid a central authority, is defeated. Not only that. The other problem is there can be no enforcement without the ability to exert force, and by design a blockchain cannot be changed by use of force, only by "consensus". So the courts would be powerless to enforce anything on a blockchain, even if they wanted. In short, blockchains are designed in a manner that makes them antithetical to property rights. I think most people want property rights and therefore will steer clear of blockchains.
