Sticking point seems to be bearings as they're likely to be viewed as a consumable component (innertubes, brake pads etc.). However, there are bearings that are subjected to loads, speeds and abuse far in excess of what bikes are subjected to (think oil drilling rigs, monster earth moving machines etc.). It doesn't seem unreasonable to expect that these bearings could last for more than a hundred years in a bike application, so I'd argue that using massively over-engineered bearings could create a HPAB that'd would probably outlast its owner.
