I just checked.

The most recent block mined was clearing even some 1 sat/vB transactions.

LN will scale for you today, tomorrow, next year, maybe even for the next decade.

There's nothing that is in concrete that blocks will not ever increase in size. Just that there is no urgency for that to happen today. Or next year, or maybe not even in the next decade.

L2's have removed that on-chain pressure.

So you still have the ability for an on-chain channel, today, without a high fee.
