Ecash is an inherently imperfect system due to its trust issues, so I want to build better things on top of bitcoin, and I suspect you agree. But I recommend against letting the perfect become the enemy of the good. I think ecash is good-but-imperfect, and there are circumstances where it is the best option available, at least for now. I will keep working to make better things, but in the meantime, wherever ecash is an imperfect but good solution, I will try to use it and be thankful -- and keep working to make better things.
