The LN would want to disable bitcoin settlements for the same general reasons that the US government decided to end the convertibility of the US dollar to gold or silver.
Hey, it is possible. That is another way of saying Bitcoin fails, which I don't consider unlikely necessarily.
I do think there is a significant incentive on the part of payment recipients to mitigate counterparty settlement risk by accepting payment on collateralized channels. In finance (outside of low-value consumer, and sovereign debt), collateral is the rule not the exception. Naked credit is the exception.
Well see how it works out. It is a certainty that LN will be deployed. It is not a certainty that it will work well or that people will use it.
So transacting in unbacked filthy fiat, is that "collateralized channels"? Or "Naked credit"? These things are pretty confusing...
