I think what they really mean is private "Person-to-Person" payments. Is that really a big market? What is the typical use case? Personally, I can't even remember when I privately paid something to a person last time. Paying for professional products and services is still a pain though. Because usually I don't want to give away private data just to pay for a coffee. And merchants dislike central services because of fees and uncertainty. But that can't be solved by a centralized service. I expect Crypto to solve that at some point. But Bitcoin seems to still have a long way to go before it can do that. The Lightning Network is a step in the right direction, but onboarding is still too slow because it takes an onchain transaction. So there still needs to be a technological advancement before crypto can handle small payments. Looks like we will have to live with a lacking payments system for the foreseeable future.
