Im talking about txn fees being paid exclusively to L2 validators rather than L1 miners. Liquid doesnt pay miners, blockstream and the federation or whatev make the txn fees. Botanix spiderchains is a new example of a remora chain that will have users but not pay txn fees to BTC L1 miners. Stacks does/did this too it has users. You can have other scaling "solutions" like WBTC that simultaneously drive demand for BTC but gives txn fees to a competitor network, if WBTC txns were RSK txns there would be (napkin math, rsk has 3500 btc payin 1 btc per month in txn fees to L1, wbtc like 150k, zero fees to L1) another 50 BTC per month in txn fees, probably way more though. May seem small now but in 8 years the added txn fees will be essential for the security of the network.
