I can see your point, but is the introduction of dark energy in the current favored model better? Instead of having an energy coming from nowhere that increases

I can see your point, but is the introduction of dark energy in the current favored model better? Instead of having an energy coming from nowhere that increases particle mass, we have something coming from nowhere that expands space.

It's locally conserved everywhere. It has to be: the covariant derivative of the metric is identically zero, and the "stress-energy tensor" of dark energy is just a constant times the metric.
