Pathogenic microbes such as lawn diseases are much more likely to thrive if the aerobic microbes are continuously stifled in their growth...

So,,, for those 2 reasons I believe that allowing the soil surface to dry out once in a while, or often, is superior as a "cultural practice" to always keeping the soil damp...
The conclusion for me is that when the phrase "Proper Irrigation" is used,,, it is refering to allowing the surface to dry...

I gave 2 reasons as to why I believe what I believe... what reasons are for the other side???
There are good reasons for allowing the surface to dry between irrigation events, none of which you have mentioned. The stuff you have mentioned are mostly inaccurate assumptions and opinions with little to no basis in fact. Further, "proper" irrigation has nothing to do with soil moisture at the surface.
