You just need to adopt your riding style a bit with frequent 'stand-n-hammer' intervals. Therefore you need a stiff frame. This won't be for everyone, admitted, but it is suitable for many. Interestingly, single speed riders range also top in hill climbing and marathon competitions.
I've tried this out a few times too, but throw in a headwind, toss in some uphill gradients, maybe even some fatigue, and I appreciated every gear I had!
Spread all them ingredients across a longer distance, and I think gearing then becomes a 'must'..
for me at least..
