"Authentic" bitcoiners may choose on-chain transactions, but I suspect they'll only do so until/unless the fees get too high for too long. Then we'll see how authentic they are. People should remember: rising fees and the emergence of fee markets are *expected behavior* for Bitcoin as adoption accelerates. This will in turn drive adoption of L2's, including LN.

As far as whether LN benefits miners... well sure, in that it creates MEV on channel open/close transactions. This is only part of the tapestry of activity that Satoshi expected to be happening on-chain in the future: securely moving large sums of money, L2 operations (LN, liquid, etc.), as well as whatever other activity the base protocol supports... yes, this includes ordinals and BRC-20 tokens, like it or not!
