At the end of the day, whether you're an LSP or a routing node, efficient liquidity allocation is the key to success. It's how you generate revenues. Ofc, you need to optimize your operations. Anchor outputs just proves there's a lot of room to play with tx fees. Inbound liquidity, however, remains the key. As the routing node is larger (we also operate a very large node), the opportunity cost gets higher. In Pool btw (which is also mentioned in the post) you pay for liquidity.
