I know such view is quite common, but if I want to avoid statistical physics, it is hard to introduce entropy first and then temperature as a derived concept. Historically, the temperature is assumed first and the entropy is derived, by the consideration of Carnot cycles - this is the way entropy was discovered. So I wonder whether there is some non-statistical, non-entropic argument for the positive temperature, which would make the historical path more sensible.
That may of been the order the phenomena were discovered but that doesn't change the fact that entropy is more fundamental to nature. Newtons laws may of been discovered before QM, but QM is still more fundamental, for example.
