Agreed. While I can't see myself needing this service any time soon, clearly it's a problem big enough to build out physical infrastructure to solve.
If the buffer box company had closer relationships with amazon's distribution and that other company that wants to do any deliveries in an hour, there could be an interesting market in the future.
There's an opportunity cost though. A product that's solving a specific pain point can be good and even profitable, but it's never going to take off the way a truly disruptive product does.
I suspect what's happening is that startups themselves, like everything else, are being commoditized.
