No, it’s simply recognizing that competing systems match or exceed on security without the same cost. You’ve effectively acknowledged this by saying that the system will be more usable and affordable by using something better designed which eventually clears in Bitcoin to reduce the number of expensive transactions.
You leave out other characteristics that make Bitcoin an attractive economic good, when you think that matching or exceeding the security at a lower cost is a valid argument against Bitcoin. If it was all about power consumption, Bitcoin wouldn’t keep increasing in demand and price.
Look, you can theorize all you want about the inefficency of Bitcoin, but the market has spoken and continues to speak.
Except, in good old libertarian fashion, they tend not to pay for it. First, the vast majority of the around $100 it costs to process a BTC transaction comes not from explicit fees, but from (invisible) money supply increase (the mining reward). That still neglects the environmental externalities, which are probably in the $30+ region.
This is a logic error: securing a financial system is not waste but paying more than you need to is. If my bank secured my money by paying an army of dudes with guns to sit around watching cash and did transfers by putting a check on the corporate jet, I’d say that was wasteful, too.
Similarly, the argument that the current system could be matched by L2 systems is both speculative and conceding defeat: even if that worked as well as the sales pitch claims it’d be using more power, and we know that there’s no plausible scenario where usage goes up while power consumption goes down.
The argument that L2 systems is the answer is also directly undercutting your earlier marketing pitch. If the justification for the inefficiency is that it’s needed for security, telling people that they should switch to your I Can’t Believe It’s Not A Bank is either admitting that the security benefits are either not real or necessary, or that they can be provided more cost effectively.
The only people who are committed to using Bitcoin are the people who’ve already bought in: everyone else is going to look for advantages relative to what they’re already using. It’s not just enough to handwave about how the system might at some point be less distant from parity, you need a serious plan for being better at something before you’ll see any significant adoption. Parity might seem like a far off goal, and it is, but it’s not enough to get most people to switch.
I’m saying also that L2 (and L3, … Ln) is a way to scale the number of users without increasing power consumption. Every time you add a layer, there are other trade-offs for the benefits gained. But at the base layer you still have the benefits of not having a central authority censoring and controlling exchange of an economic good.
For the second point, are you talking about Layer 2 solutions that track cryptocurrency in a centralized database, like an exchange, where most transactions happen? Basically just traditional banking but with crypto as the unit of account. Or are you talking about decentralized layer 2 solutions like Lightning Network? I don't think Lightning Network can scale to match what the banking sector does, even if you ignore all the services banks provide other than facilitating transactions. For example you could not pay the US workforce with Lightning Network because it would take several months worth of of blocks just to open a channel to each person, and quickly those channels would run out of inbound capacity and you'd need to open more on top of that, so the Layer 1 capacity still limits the ability to use LN at that scale.
Already now you can get a VISA/Mastercard and use that to spend Bitcoin. But of course, every layer on top of Bitcoin presents its own set of trade-offs in terms of trust and security.
What constitutes waste is completely subjective.
Bitcoin is like that times 1,000,000 when it comes to energy usage.
The energy and resources expended mining for diamonds is wasteful also.
This is your first mistake: the traditional banking system does not have a security model predicated on the ability to waste power. Bitcoin does, and it’s dynamic so there’s no way to waste less power which isn’t explicitly ceding control.
The second error is treat the two as comparable without recognizing that one of them is used daily by millions of people making billions of transactions, and the other has almost no real world adoption. That matters in two ways because it’s not just that bitcoin uses more power to do so much less but also that the real financial system has higher power draw for work in addition to processing transactions. For example, Visa can do on the order of tens of thousands of transactions per second versus Bitcoin’s 7 but if you are looking at how much power they use, the figures will include running a ton of anti-fraud and other support systems which Bitcoin is missing.
The second error is implicitly assuming that the number of people Bitcoin serves is correlated with it’s power usage. You could serve the same number of people as the banking sector does now without increased power consumption when you bring layer 2 or 3 solutions into the picture.
Money is so ingrained into people's lives that they think it has true value. The fact is that it represents people's work and efforts. The funny part is that without it no one works together. We need a currency that lets us better work together. A currency with a fixed amount will increase the competition to get it therefore increasing disparities. Another funny thing about people is that we dislike to share so those who have will be less likely to share since they know that it's going to be so much harder to get it back. It can't work to make a better world.
Bitcoin is the start but we'll see a better coin with better properties that will make it a true replacement for the Dollar in the future.
For now, its role is and will continue to develop as a digital replacement for gold as a store of value.
