The current real world application is a test to see how money or forms of value can be coordinated among distributed decentralized networks. Just the experimentation is a value and benefit for humanity. One should remove the idea that Bitcoin will be the winner as a payment system. It could be Bitcoin with its Lightning Network implementation, or it could be something better. As it seems scalability is your specific gripe here, there are competing distributed ledger technologies that are working towards or already have solved this to an extent better than Bitcoin. Understand that this goal of scalable, decentralized multi-nodal coordination is not an easy and simple problem, but it is a problem that market participants are working towards, and solutions are necessarily constantly evolving, because is that not what markets do?
