It seems pretty much all rock you get today is going to be mined then farmed. The porosity is a valid point. The first layers of strata in a limestone deposit are porous, Being the most recently deposited layers. As you get deeper into the stratigraphy, porosity is reduced do to pressure and chemical precipitation.
The live rock fm the “good old days” was obtained fm surface reefs by use of explosives, i.e. abundance of life and porosity.
