where does bitcoin have privacy on L2? were you talking about ruggable ecash mints or were you talking about maintaining your own payment channels in an extremely specific and difficult way?
how come nobody is slinging pounds of MDMA using this so-called privacy on L2? it's not like those people haven't changed their own business processes an uncountable number of times in order to maintain best practices. the privacy you have on layer 2 is a toy.
