My post was just to clarify that it's a problem to lace inner over outer on 1x builds, certainly one can build 1x if you don't interlace at the cross. As to the merit of lacing the cross, that's a different technical question.

It's been standard practice to lace the crossed spokes inner over outer for about a century.

The main benefit is that it builds a bit of resilience into the wheel by virtue of the slight bend the spokes make at the crosses. Under high stress the spokes can lengthen by straightening and transferring some of the load to their neighbor.

I don't know if it makes as much difference with today's heavier rims, but it does with the lighter rims. Non-laced (inner over outer) builds have very similar mechanical properties to radial builds. And like with radial builds sudden shock loads can cause stress cracked rims, and cracked hub flanges.

Doesn't mean that Easton is wrong, assuming they know the implications and engineered accordingly.
