A perspective:
I would love to obtain and build up a bike using a Rohloff hub. I currently have 5 bikes (three of my kids use them, one is a touring build, and one is my commuter) using Shimano Nexus-7 internal hubs. I have found my commuter nexus-7 to be rock solid, --AND I consider it my experiment in non-maintenance. I do absolutely nothing to that bike but fix whatever stops working. In 4 years I've replaced exactly one rusting and neglected chain (and am maybe due for another soon).

I'm not sure I would gain anything from a Rohloff for the huge cost increase. And the down side of internal hubs (only one I can determine) is the significant increase in complications for pulling the rear wheel off to fix a flat. Standard derailed rear wheels pop right off and back on. Internals have to be disconnected and re-connected to the gear shift mechanism, and have to be aligned correctly. I am totally comfortable doing that for my bike --but I build these things. If my kids had a flat somewhere, someone unfamiliar with the linkages would have trouble.
