> which is responded lightning solves that

Theoretically.

In practice, it has shown that it is only viable if adoption by number of nodes and TVL grew by orders of magnitude, and both are very unlikely to happen because - like I said - spenders have nothing to gain from it and no matter how much of the UX friction is solved, it will never be as easy as paying with credit card.

The only people who want to use Lightning are the ones who are invested in Bitcoin. Everyone else just want simple/safe access to a payment network.
