inflation will make both consumers and vendors look for ways to shave their margins thinner
and yes, services like Xapo bank already do this via the credit card payment network
but with higher margins than LN can do, that's my point... when people are squeezed, they will eventually consider the saving to be worth the time to learn and deploy
the cards use case just is a problem
i live in madeira, and almost nobody except the big chains and centrally located shops has card terminals
they would sooner adopt LN if enough customers demanded it, because the cost of deployment of the setup is very low, they almost all have mobile phones that can already act as lightning payment terminals
