BTC is 100% trackable and wallets have been earmarked by governments for seizure and complete blockage. It is NOT good enough for free market. Also transactions made very slow and of varying expense. Cannot scale like that. So what the hell are you talking about. It cannot support free financial transactions with safety and at scale.

He did say 'if", guaranteeing that it will not stay decentralized.
I share your sceptical view. Nevertheless it's the best approach so far, as there's global trust in the fairness of BTC. Lightning is not the way to onboard the rest of the world, but I'm sure it's not the end of the game.
No there is not. For a while there was a lot of merchant adoption. Then fees got too high and throughput dropped and less and less merchants supported it. Lightning has helped some but there are still problems. Many parts of global south are more likely to use stablecoins than BTC. Dash has been popular for daily payments for lower fees. Where freedom from transaction surveillance and control is needed many turn to XMR and other privacy coins which also have low and stable fees. As long as BTC has small blocks the throughput problem remains and even adding second layers only goes so far.
