That still remains to be seen, but the bigger it gets, the more it could be use as a global settlement network. Strike and Bottlepay are using it for that purpose. Taro could improve it for that purpose.
Bitcoin's base layer can process about as many annual settlements as Fedwire, and can do so in a decentralized way that anyone can connect to rather than being a closed sysetm. I think that's a pretty big deal.
