Your hysterics aside, almost all of that is patently false, and in most
locations is directly contrary to code. You really need to study what a
Ufer ground is and why they work.
By the way, this same old wives tale comes up every so often here and on
other forums, and each time it does I spend about a half hour doing
Google searches to find any documented instances of a block of concrete
exploding because of steam expansion from a lightning strike. I have
found TONS of discussion and endless repetitions of the same old
exhortation you just made, but not a single first hand account of
exploding concrete due to steam. Concrete is quite brittle and
fractures easily, and I could far better imagine that the intense
thermal shock generated by a lightning hit would instead be the
culprit. I have indeed witnessed first hand a lightning strike blasting
a chunk out of solid granite rock alongside the road I was driving on
(scared the hell out of me), and I guarantee that rock was dry as a bone.

into the concrete base !!!!!!! NEVER use any ground rods in

If you would get a lightening strike, the current would carry into the
concrete
and boil off the water. When this happens the concrete will explode !!!
