So, if I used a single coax line grounding block like below, it would have to be mounted somewhere inside the house so that I could tie into a single point earth ground (like a copper pipe).

Stated was what is required. The antenna must connect to its own earth ground. And the antenna lead must route so make that single digit connection to single point ground. That ground block inside says you still did not grasp what was written.

Protection means energy does not enter a building. If energy does enter and if that energy is sufficient to blow through protection already inside every appliance, then nothing inside will avert that damage. With or without an interior protector, you have same protection. Nothing inside does effective protection. Protection is always about where energy dissipates.

Every wire inside every incoming cable must make that short connection to earth before entering. You reroute any cable that does not.
A problem created because too many installers only understand code; do not learn what is also required for surge protection. A utility explains how to kludge a solution only if the superior solution cannot be implemented. How to enlarge a single point ground so that every incoming wire still makes that necessary short connection:
