There is no updating of arguments necessary. The problem in Bitcoin today are the same problem that have existed for years. That problem being that there are too many people focused on esoteric solutions, like watchtowers, 2nd layers, and even 3rd layers, that only developers care about. And not enough people talking to customers or merchants, and building things that make Bitcoin work as an actual currency. Seeing as the whole point of this stuff is to work as a currency, it seems like this should be important. It is a rare few companies, such as BitPay, that are building things like point of sale devices that actually make it possible for consumers to buy things from merchants.
