By this logic, I can create an application that transposes the entire transaction history of BTC to a plain old database and have the same utility. BTC's utility is in it's ability to perform future transactions, not in it's ability to maintain a ledger of transactions that have occurred in the past.
Immutable ledgers are not new or specific to blockchain; they have existed for decades. What is unique about crypto currency is how that immutable ledger is appended. In your hypothetical example above of BTC being reduced to one node, you are correct that we could still verify the integrity and information of the ledger with that single node, but that single node would now be able to write whatever it wants to the ledger.
You're not wrong but let's get back to the gold analogy for a minute. (I'm going to dumb it down, not for you or shefcurry but for others who don't quite understand the granular details of how cryptology works.)
Pretend I have all the remaining gold that the world has produced and ever will produce in a locked room that is impenetrable and the key to the room is an encrypted cypher. Let's also imagine that it would take 168 years to penetrate the vault full of gold (which is exactly the same time it would take a single node to mine 2016 blocks.)
One outcome is that humanity doesn't bother with the project of waiting and forgets a time when gold had any value at all. Could this happen to Bitcoin? I absolutely concede that is a possibility. There might be a time in the future when Bitcoin goes to zero because it's so impractical to carry the cost of the network due to a breakdown in the grid or something else.
Another outcome is that people who are motivated by wealth will simply do everything they can (even risk their lives) to get the gold. By the way, there are several dead bodies throughout the tombs within the Egyptian pyramids of dead thieves who risked it all to get at the treasure. It's one of men's predictable traits.
deck wrote:What shefcurry was getting at, is that at a certain price point of BTC, the cost to compute the next hash (primarily in terms of electrical consumption) can exceed the value awarded to the miner. If this happens, the currency will likely fail, or transaction costs on the network will go up substantially. We were getting precariously close to this in late 2022. Core Scientific (a relatively large BTC miner) filed for bankruptcy when prices were floating around $17k. It's likely that lots of miners are operating at a loss right now at around $20k, with them betting on the price of the BTC they are able to retain going back up. So no, this isn't a risk that is only realized in some end of world scenario where mankind is challenged with computational power, this is a potential risk right now.
There have been bear markets in the past that nearly crushed most if not all hard assets. If you remember for example back in 1999 the US dollar was outperforming gold which lasted several years (gold was flat at barely 300 dollars an ounce) and it wasn't until 2004 that gold was back on par with the US monetary base. When something like that happens, you're running mining equipment and manpower at a net loss to the point where entire mines collapse. This is obviously part of the asset cycle but what you don't do is destroy the mining equipment, rather; you either re-purpose it for something or store it until it's time to mine again.
The point is that during these cycles you will inevitably have a downsizing of the overall infrastructure but that doesn't mean its going away forever, that would be stupid.

deck wrote:Sure, but how useful is this in practice? We have been able to do peer-to-peer transactions for sometime now. What exactly is the revolutionary utility of BTC or the Lightning Network? What is BTC allowing us to do that I can't already do today? I for one will never make use of BTC or Lightning, as the idea of my transaction history being written to a public ledger that anyone can access is horrific. Lots of hay is made about the fact that with BTC we can transact across boarders quickly, or perform other peer-to-peer transactions quickly. What is lost in those statements is that the current global payments systems don't take time to transact due to some technical limitation, those existing networks are slow to transact due to AML, Fraud, and Sanctions checks, or more simply, due to regulation and the need to provide consumer protections.
Personally I don't even care about the lightning network atm. I'm not hodling BTC for its utility just like I don't hold gold for its utility, I have it because of its scarcity. Regardless, we're still in the early days of crypto payment solutions etc.
