Here is my original note which started this conversation. If you think my point boils down to "empty mempools bad" you are having trouble understanding.
My point was just that Monero scales worse then Bitcoin on L1 and has almost no fees because it has very few users. Yes, blocks are dynamic, but it doesn't matter if you have 12 transactions per block.
Liquid is not a shitcoin network, it is a Bitcoin denominated sidechain with different tradeoffs. So the network effects and economics of Bitcoin apply to it. It is just a tool, not a currency itself. Monero is a shitcoin with a floating exchange rate so it gets harsher treatment.
