You are missing the point about tire inflation. I agree that lower pressure doesn't cause spoke tension problems. Higher pressures cause deformation of rim which have an effect on the spoke tension that may no have been accounted for when building. I would also say that impacts of the rim on the ground are going to cause momentary cycling of an individual spoke's tension which could lead to fatigue issues if done often enough.

I would disagree about spoke breakage being due to bad spoke tensioning only. Tension is part of it but so is using spokes that are too small a diameter for the load that they are being used for. A spoke with a 1.5mm elbow isn't going to have the longevity of one with a 2.0mm elbow or a 2.3mm elbow. Thicker elbows have a significant impact on the amount of stress the spoke can take before it breaks.

Wrong and insulting.
