I agree with you regarding sales and why its effective in real-time, but it doesn't have to be that way — technology is rapidly changing that, software is getting so good you can now just signup for products you'd typically previous have to talk to a human to use.
I think this trend will continue, and with Journey my belief is we can accelerate that even more with powerful marketing tools.
I would add that sales is absolutely also storytelling - a great example is fundraising! I joined a B2B technology company (AdRoll) and worked there for 4 years and saw first hand how effective sales people sell - by telling stories, not reading from slides.
