Well first of all it well never scale and Andreas can atest to that in this video: https://www.youtube.com/watch?v=pT9kJq_Ogrk. Even if scaling is a moving target and never makes it there, the current speed of which we have transactions is okay. Sure not many people can use the network, but the infrastructure exists and if it stays this current way I don't see a reason why Bitcoin wouldn't have value. It may not have value of 7k but it could easily have value between $500-7000.
