That is because they are doing it wrong.

Ever wonder what happens to the rain water that collects in the tower legs?

Mine drains into the soil.  If you block the ends of the tower legs with 
concrete, the rainwater rots your tower legs from the inside out.  My 
tower has been up since 1976 with no sign of corrosion.

 Maybe they just want to sell ground rods and cad welding equipment and 
tower sections.
