Nobody argues otherwise. But claiming that condensation caused by
halfways empty tanks is a noteworthy source for that water is equally
absurd. If there is water in your tanks, chances are you buyed it at
fuel price. Another important source is a leaking seal while the plane
is parked in the rain.

But you're correct in one way: If you always fill the tanks after each
flight, there won't be water in the tanks. No, not because there is no
condensation, but because you will have to drain a couple of gallons
before the each flight.
