I agree in principle, but I think that there are fundamental problems with Bitcoin that make it intrinsically unsuitable for its stated purpose of being a decentralized world currency. Any success it makes along that axis essentially occurs
in spite of itself, based on the commitment of people who are riding the hype wave to try to make something good of it.
If people were honest, they'd admit that Bitcoin is flawed, that it was never intended or conceived as the perfect realized implementation of a digital currency, etc. It's a thought experiment that grew rapidly out of control.
The Lightning Network is a good example of an earnest try to make something workable out of Bitcoin, but even that has real difficulty overcoming some of bitcoin's core design flaws, which are: a) difficulty mechanism blocking out commodity miners and essentially assuring there will always be centralization, which means network security will always be dubious at best, fees will always be high, and other undesirable consequences; b) inability to provide reliable, rapid transaction confirmations; c) inherent scalability difficulties based on the amount of work needed to verify transactions.
Lightning networks address some of this for some partners, but even for those who find lightning networks a reasonable workaround (that is, those with sufficient btc to open, maintain, and populate mutual funding channels), there are additional negative trade-offs that make the process undesirable (if the counterparty can prevent them from crying 'foul' within the settlement deadline, a lot of money can be successfully stolen).
Continued insistence on Bitcoin/blockchain deployment as such is non-productive. Lessons should be extracted from the bitcoin experience and we should move on to something that tries to resolve Bitcoin's fundamental issues. Let's accept Bitcoin's role as a thought leader and early implementation of digital currency, but stop pretending that it's ever going to be useful as a major economic backbone.
