I think that the area where you want fault-tolerance the most is decentralized cash. If you are going to take control of your money you better do it in a fault-tolerant system. Many people don't care about it today but there are those who do. That's why cryptocurrency is the real killer app for blockchain, like it or not.
To your comments re bitcoin, it sounds to me like somebody complaining that Internet is slow back in the 90s/00s.
EDIT:
I am not pontificating in favor of bitcoin. It's just that the technology is still immature but there is a lot of great and promising work happening today.
